Baja California Sur
–
Before becoming a state on October 8,1974, the area was known as the South Territory of Baja California. It is bordered to the north by the state of Baja California, to the west by the Pacific Ocean, the state has maritime borders with Sonora and Sinaloa to the east, across the Gulf of California. The state is home to the tourist resorts of Cabo San Lucas and its largest city and capital is La Paz. The state is the part of the Baja California Peninsula. With a territory of 73,909 km², it is about 750 km long, the state is divided into five municipalities. Comondú is located in the center of the state with its seat at Ciudad Constitución and it borders the municipalities of Mulegé, Loreto and La Paz with the Pacific Ocean to the west. Mulegé is in the north of the state with its capital in Santa Rosalía and it borders the municipalities of Comondú and Loreto with Baja California Norte to the north, the Pacific Ocean to the west and the Gulf of California to the east. It accounts for almost 45% of the state’s territory, the municipality of La Paz is in the south of the state. It is the second largest municipality, accounting for just over 27% of the territory of the state and it borders the municipalities of Comondú and Los Cabos and extends from the Pacific Ocean to the Gulf of California. The municipality of Los Cabos is at the tip of the state, with its seat at San José del Cabo. The municipality is one of the most important tourist destinations in Mexico, the municipality borders that of La Paz to the north, with the rest defined by the Pacific Ocean and the Gulf of California. The municipality of Loreto is in the center of the state and it borders the municipalities of Mulegé and Comondú with the Gulf of California to the east. Its major cities are La Paz, San Jose del Cabo, Ciudad Constitución, Santa Rosalia, the territory is primarily mountains or mountain ranges and coastal plains. The mountain ranges parallel the coastline and are of volcanic rock, the local name for the main mountain range is the Sierra de la Giganta and the highest peak is the Sierra de la Laguna at 2080m above sea level. The coastal plains are significantly wider on the Pacific side, averaging about 40 km, with much wider plains such as those of Santa Clara, Berrendo and these areas are dominated by sedimentary rock, especially limestone of marine origin. The state is divided into five regions, Central Desert, La Serranía, the Vizcaíno Desert, the Central Desert has desert plants, with vegetation springing up during short and irregular rains. The La Serranía is the mountain areas with significant tree cover. The Magdalena Plains is a large, flat area near the Pacific coast, the climate of the state is dry, with an average annual temperature of 18–22°C and average annual rainfall of less than 200mm

Metropolitan area
–
As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions. The Greater São Paulo is a term for one of the multiple definitions the large metropolitan area located in the São Paulo state in Brazil. A metropolitan area combines an urban agglomeration with zones not necessarily urban in character and these outlying zones are sometimes known as a commuter belt, and may extend well beyond the urban zone, to other political entities. For example, El Monte, California is considered part of the Los Angeles metro area in the United States, in practice, the parameters of metropolitan areas, in both official and unofficial usage, are not consistent. Population figures given for one area can vary by millions. A polycentric metropolitan area is one not connected by continuous development or conurbation, in defining a metropolitan area, it is sufficient that a city or cities form a nucleus that other areas have a high degree of integration with. The Australian Bureau of Statistics defines statistical divisions as areas under the influence of one or more major towns or a major city. However, this definition has become obsolete with the conurbation of several statistical divisions into a larger metropolitan areas. In Brazil, metropolitan areas are called metropolitan regions, each State defines its own legislation for the creation, definition and organization of a metropolitan region. The creation of a region is not intended for any statistical purpose, although the Brazilian Institute of Geography. Their main purpose is to allow for a management of public policies of common interest to all cities involved. They dont have political, electoral or jurisdictional power whatsoever, so living in a metropolitan region do not elect representatives for them. Statistics Canada defines a metropolitan area as an area consisting of one or more adjacent municipalities situated around a major urban core. To form a CMA, the area must have a population of at least 100,000. To be included in the CMA, adjacent municipalities must have a degree of integration with the core. As of the Canada 2011 Census, there were 33 CMAs in Canada, including six with a population over one million—Toronto, Montreal, Vancouver, Ottawa, Calgary and Edmonton. In Denmark the only area is Greater Copenhagen, consisting of the Capital Region of Denmark along with the neighboring regions Region Zealand. Greater Copenhagen has an population of 1.25 million people

Luke the Evangelist
–
Luke the Evangelist is one of the Four Evangelists—the four traditionally ascribed authors of the canonical Gospels. The New Testament mentions Luke briefly a few times, and the Pauline epistle to the Colossians refers to him as a doctor, Christians since the faiths early years have regarded him as a saint. He is believed to have been a martyr, reportedly as having been hanged in an olive tree, though some believe otherwise. Many scholars believe that Luke was a Greek physician who lived in the Greek city of Antioch in Ancient Syria, though other scholars. Bart Koet for instance considered it as widely accepted that the theology of Luke–Acts points to a gentile Christian writing for a gentile audience, gregory Sterling though, claims that he was either a Hellenistic Jew or a god-fearer. His earliest notice is in Pauls Epistle to Philemon—Philemon 1,24 and he is also mentioned in Colossians 4,14 and 2Timothy 4,11, two works commonly ascribed to Paul. He had become a disciple of the apostle Paul and later followed Paul until his martyrdom, having served the Lord continuously, unmarried and without children, filled with the Holy Spirit he died at the age of 84 years. If one accepts that Luke was in fact the author of the Gospel bearing his name and also the Acts of the Apostles, the we section of Acts continues until the group leaves Philippi, when his writing goes back to the third person. This change happens again when the returns to Philippi. There are three we sections in Acts, all following this rule, Luke never stated, however, that he lived in Troas, and this is the only evidence that he did. The composition of the writings, as well as the range of vocabulary used, a quote in the Letter of Paul to the Colossians differentiates between Luke and other colleagues of the circumcision. 10 My fellow prisoner Aristarchus sends you his greetings, as does Mark,11 Jesus, who is called Justus, also sends greetings. These are the only Jews among my co-workers for the kingdom of God,14 Our dear friend Luke, the doctor, and Demas send greetings. This comment has traditionally caused commentators to conclude that Luke was a Gentile, if this were true, it would make Luke the only writer of the New Testament who can clearly be identified as not being Jewish. However, that is not the only possibility, although Luke is considered likely to be a Gentile Christian, some scholars believe him to be a Hellenized Jew. The phrase could just as easily be used to differentiate between those Christians who strictly observed the rituals of Judaism and those who did not. Lukes presence in Rome with the Apostle Paul near the end of Pauls life was attested by 2 Timothy 4,11, Only Luke is with me. In the last chapter of the Book of Acts, widely attributed to Luke, we find several accounts in the first person also affirming Lukes presence in Rome including Acts 28,16, And when we came to Rome

City
–
A city is a large and permanent human settlement. Cities generally have complex systems for sanitation, utilities, land usage, housing, a big city or metropolis usually has associated suburbs and exurbs. Such cities are associated with metropolitan areas and urban areas. Once a city expands far enough to another city, this region can be deemed a conurbation or megalopolis. Damascus is arguably the oldest city in the world, in terms of population, the largest city proper is Shanghai, while the fastest-growing is Dubai. There is not enough evidence to assert what conditions gave rise to the first cities, some theorists have speculated on what they consider suitable pre-conditions and basic mechanisms that might have been important driving forces. The conventional view holds that cities first formed after the Neolithic revolution, the Neolithic revolution brought agriculture, which made denser human populations possible, thereby supporting city development. The advent of farming encouraged hunter-gatherers to abandon nomadic lifestyles and to settle near others who lived by agricultural production, the increased population density encouraged by farming and the increased output of food per unit of land created conditions that seem more suitable for city-like activities. In his book, Cities and Economic Development, Paul Bairoch takes up position in his argument that agricultural activity appears necessary before true cities can form. According to Vere Gordon Childe, for a settlement to qualify as a city, it must have enough surplus of raw materials to support trade and a relatively large population. To illustrate this point, Bairoch offers an example, Western Europe during the pre-Neolithic, when the cost of transport is taken into account, the figure rises to 200,000 square kilometres. Bairoch noted that this is roughly the size of Great Britain, the urban theorist Jane Jacobs suggests that city formation preceded the birth of agriculture, but this view is not widely accepted. In his book City Economics, Brendan OFlaherty asserts Cities could persist—as they have for thousands of years—only if their advantages offset the disadvantages, OFlaherty illustrates two similar attracting advantages known as increasing returns to scale and economies of scale, which are concepts usually associated with businesses. Their applications are seen in more basic economic systems as well, increasing returns to scale occurs when doubling all inputs more than doubles the output an activity has economies of scale if doubling output less than doubles cost. To offer an example of these concepts, OFlaherty makes use of one of the oldest reasons why cities were built, in this example, the inputs are anything that would be used for protection and the output is the area protected and everything of value contained in it. OFlaherty then asks that we suppose the protected area is square, the advantage is expressed as, O = s 2, where O is the output and s stands for the length of a side. This equation shows that output is proportional to the square of the length of a side, the inputs depend on the length of the perimeter, I =4 s, where I stands for the quantity of inputs. So there are increasing returns to scale, O = I2 /16 and this equation shows that with twice the inputs, you produce quadruple the output

Mexico
–
Mexico, officially the United Mexican States, is a federal republic in the southern half of North America. It is bordered to the north by the United States, to the south and west by the Pacific Ocean, to the southeast by Guatemala, Belize, and the Caribbean Sea, and to the east by the Gulf of Mexico. Covering almost two million square kilometers, Mexico is the sixth largest country in the Americas by total area, Mexico is a federation comprising 31 states and a federal district that is also its capital and most populous city. Other metropolises include Guadalajara, Monterrey, Puebla, Toluca, Tijuana, pre-Columbian Mexico was home to many advanced Mesoamerican civilizations, such as the Olmec, Toltec, Teotihuacan, Zapotec, Maya and Aztec before first contact with Europeans. In 1521, the Spanish Empire conquered and colonized the territory from its base in Mexico-Tenochtitlan, Three centuries later, this territory became Mexico following recognition in 1821 after the colonys Mexican War of Independence. The tumultuous post-independence period was characterized by instability and many political changes. The Mexican–American War led to the cession of the extensive northern borderlands, one-third of its territory. The Pastry War, the Franco-Mexican War, a civil war, the dictatorship was overthrown in the Mexican Revolution of 1910, which culminated with the promulgation of the 1917 Constitution and the emergence of the countrys current political system. Mexico has the fifteenth largest nominal GDP and the eleventh largest by purchasing power parity, the Mexican economy is strongly linked to those of its North American Free Trade Agreement partners, especially the United States. Mexico was the first Latin American member of the Organisation for Economic Co-operation and Development and it is classified as an upper-middle income country by the World Bank and a newly industrialized country by several analysts. By 2050, Mexico could become the fifth or seventh largest economy. The country is considered both a power and middle power, and is often identified as an emerging global power. Due to its culture and history, Mexico ranks first in the Americas. Mexico is a country, ranking fourth in the world by biodiversity. In 2015 it was the 9th most visited country in the world, Mexico is a member of the United Nations, the World Trade Organization, the G8+5, the G20, the Uniting for Consensus and the Pacific Alliance. Mēxihco is the Nahuatl term for the heartland of the Aztec Empire, namely, the Valley of Mexico, and its people, the Mexica and this became the future State of Mexico as a division of New Spain prior to independence. It is generally considered to be a toponym for the valley became the primary ethnonym for the Aztec Triple Alliance as a result. After New Spain won independence from Spain, representatives decided to name the new country after its capital and this was founded in 1524 on top of the ancient Mexica capital of Mexico-Tenochtitlan

Los Cabos Municipality
–
Los Cabos is a municipality located at the southern tip of Mexicos Baja California Peninsula, in the state of Baja California Sur. It encompasses the towns of Cabo San Lucas and San José del Cabo, the area was remote and rural until the latter 20th century, when the Mexican government began to develop Cabo San Lucas for tourism, which then spread east to the municipal seat. The main draw is the climate and geography, where meets the sea, along with sport fishing, resorts. This tourism is by far the main economic activity with two million visitors per year. The town of San José del Cabo is located at the foot of the Sierra de la Laguna,130 km SSW of La Paz, although it is the seat of government for the municipality of Los Cabos, it is smaller than the other city of Cabo San Lucas. However, because of federal and private investments in tourism, its growth is now rivaling that of the famous resort area. This growth has been regulated to outside of the center, especially to the south where the beaches are, leaving the historic town center quiet. There are still cobblestone streets, adobe houses, jacaranda trees and a square in front of a church that dates from the 1700s. The art scene in the town is well-developed because of tourism and these shops carry high end paintings, sculptures in from traditional Mexican, Mexican contemporary and international artisans and artists. During the high season from October to May, these galleries stay open late into the night, the town has resisted the addition of large shopping malls and chain stores. There is also some colonial era architecture as well, but this style has more in common with towns to the north into the United States rather than the center. The main example of colonial architecture here is the parish church. It was part of the Estero de las Palmas de San José del Cabo Mission, the facade is marked with a tile mural depicting the martyrdom of founder Nicolás Tamaral, killed by the local Pericu people. The patron saint of the town is Saint Joseph, whose feast day is celebrated here on March 19, another important occasion is the feast of the Our Lady of the Pillar on October 12. Occasions like these are marked with traditional dance in dress styles known as “Flor de Pitaya” and the “La Cuera. ”Other important landmarks in the include the municipal hall, which dates from 1981. The tourist area of the town is the area between the proper and the shoreline. This area has a golf course and a line of hotels and resorts facing the ocean. San Jose del Cabo is the seat and the government for the found in a 3,451. 51km2 area

Scuba diving
–
Scuba diving is a mode of underwater diving in which the scuba diver uses a self-contained underwater breathing apparatus which is completely independent of surface supply, to breathe underwater. They may include additional cylinders for decompression gas or emergency breathing gas, closed-circuit or semi-closed circuit rebreather scuba systems allow recycling of exhaled gases. The volume of gas used is reduced compared to that of open circuit, therefore, scuba divers engaged in armed forces covert operations may be referred to as frogmen, combat divers or attack swimmers. A scuba diver primarily moves underwater by using fins attached to the feet, scuba divers are trained in the procedures and skills appropriate to their level of certification by instructors affiliated to the diver certification organisations which issue these certifications. A minimum level of fitness and health is required by most training organisations, the closed-circuit rebreathers were first developed for escape and rescue purposes, and were modified for military use, due to their stealth advantages, as they produce very few bubbles. The first commercially successful closed-circuit scuba was designed and built by English diving engineer, Henry Fleuss in 1878, while working for Siebe Gorman in London. Sir Robert Davis, head of Siebe Gorman, improved the oxygen rebreather in 1910 with his invention of the Davis Submerged Escape Apparatus, rebreathers have been increasingly used by civilians for recreation, especially since the end of the Cold War. This reduced the risk of attack by Communist Bloc forces. After that, the armed forces had less reason to requisition civilian rebreather patents. The single hose two stage scuba regulators trace their origins to Australia, where Ted Eldred developed the first example of type of regulator. This was developed because patents protected the Aqualungs twin hose design, the single hose regulator separates the demand valve from the cylinder, giving the diver air at the ambient pressure at the mouth, rather than ambient pressure at the cylinder valve. The term SCUBA originally referred to United States combat frogmens oxygen rebreathers, SCUBA was originally an acronym, but is now generally used as a common noun or adjective, scuba. It has become acceptable to refer to equipment or scuba apparatus—examples of the linguistic RAS syndrome. Scuba diving may be performed for a number of reasons, both personal and professional, recreational diving is done purely for enjoyment and has a number of technical disciplines to increase interest underwater, such as cave diving, wreck diving, ice diving and deep diving. Divers may be employed professionally to perform tasks underwater, some of these tasks are suitable for scuba. There are divers who work, full or part-time, in the diving community as instructors, assistant instructors, divemasters. Other specialist areas of diving include military diving, with a long history of military frogmen in various roles. Their roles include direct combat, infiltration behind enemy lines, placing mines or using a manned torpedo, in some cases diver rescue teams may also be part of a fire department, paramedical service or lifeguard unit, and may be classed as public service diving

Resort
–
A resort is a self-contained commercial establishment that endeavors to provide most of a vacationers wants, such as food, drink, lodging, sports, entertainment, and shopping, on the premises. The term resort may be used for a property that provides an array of amenities, typically including entertainment. A hotel is frequently a central feature of a resort, such as the Grand Hotel at Mackinac Island, some resorts are also timeshare or fractionally owned, or wholly owned condominium complexes. A resort is not always a commercial establishment operated by a single company, commonly these facilities are of higher quality than would be expected if one were to stay at a hotel or eat in a towns restaurants. Closely related to these resorts are convention and large meeting sites, generally these occur in cities where special meeting halls, together with ample accommodations as well as varied dining and entertainment, are provided. An all-inclusive resort charges a price that includes most or all items. At a minimum, most inclusive resorts include lodging, unlimited food, drink, sports activities, all-inclusive resorts are found in the Caribbean, particularly in Dominican Republic, Egypt, and elsewhere. Many also offer sports and other included in the price as well. They are often located in warmer regions, the all-inclusive model originated in the Club Med resorts, which were founded by the Belgian Gérard Blitz. Some all-inclusive resorts are designed for specific vacation interests, for example, certain resorts cater to adults, while even more specialized properties accept couples only. Other all-inclusive resorts are geared toward families, with facilities like craft centers, game rooms, all-inclusive resorts are also very popular locations for destination weddings. A spa resort is a short term residential/lodging facility with the purpose of providing individual services for spa-goers to develop healthy habits. Historically many such spas were developed at the location of natural hot springs or sources of mineral waters, golf resorts are resorts that cater specifically to the sport of golf, and include access to one or more golf course and or clubhouse. Golf resorts typically provide golf packages that provide visitors with all greens and cart fees, range balls, accommodations, in North America a ski resort is generally a destination resort in a ski area. Ski resort is less likely to refer to a town or village, a megaresort is a type of destination resort which is of an exceptionally large size, such as those along the Las Vegas Strip. In Singapore integrated resort is a euphemism for a destination resort. A holiday village is a type of self-contained resort in Europe, a holiday camp in the United Kingdom refers to a resort where the accommodation is in chalets. The term holiday park is used for a resort where the accommodation includes static caravans, there are 1500+ timeshare resorts in the U. S. that are operated by major hospitality, timeshare-specific, or independent companies

Mahi-mahi
–
The mahi-mahi or common dolphinfish is a surface-dwelling ray-finned fish found in off-shore temperate, tropical and subtropical waters worldwide. Also widely called dorado and dolphin, it is one of two members of the Coryphaenidae family, the other being the pompano dolphinfish, mahi means very strong in Hawaiian. The name mahimahi means very strong in Hawaiian, in other languages, the fish is known as dorade coryphène, dorado, dolphin, lampuga, llampuga, lampuka, lampuki, rakingo, calitos, ti-rone or maverikos. The common English name of dolphin causes much confusion, additionally, two species of dolphinfish exist, the common dolphinfish and the pompano dolphinfish. Both these species are marketed by their Pacific name, mahi-mahi. Being fish, they are not related to dolphins, see Coryphaena for the possible etymologies of dolphinfish. The fish is called mahi-mahi in the Hawaiian language, and mahi mahi is commonly used elsewhere, in the Pacific and along the English speaking coast of South Africa they are also commonly called by the Spanish name, Dorado. In the Mediterranean island of Malta, this fish is referred to as the lampuka, linnaeus named the genus, derived from the Greek word, κορυφή, koryphe, meaning top or apex, in 1758. Synonyms for the species include Coryphaena argyrurus, Coryphaena chrysurus and Coryphaena dolfyn, mahi-mahi have compressed bodies and a single long-based dorsal fin extending from the head almost to the tail. Mature males have prominent foreheads protruding well above the body proper and their caudal fins and anal fins are sharply concave. They are distinguished by dazzling colors, golden on the sides, the pectoral fins of the mahi-mahi are iridescent blue. The flank is broad and golden, out of the water, the fish often change color, going though several hues before finally fading to a muted yellow-grey upon death. Mahi-mahi can live up to 5 years, although they seldom exceed four, females are usually smaller than males. Catches average 7 to 13 kilograms and a meter in length and they rarely exceed 15 kilograms, and mahi-mahi over 18 kilograms are exceptional. Mahi-mahi are among the fastest-growing of fish and they spawn in warm ocean currents throughout much of the year, and their young are commonly found in rafts of Sargassum weeds. Mahi-mahi are carnivorous, feeding on flying fish, crabs, squid, mackerel and they have also been known to eat zooplankton and crustaceans. Males and females are mature in their first year, usually by 4–5 months old. Spawning can occur at body lengths of 20 cm, females may spawn two to three times per year, and produce between 80,000 and 1,000,000 eggs per event

Europe
–
Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, yet the non-oceanic borders of Europe—a concept dating back to classical antiquity—are arbitrary. Europe covers about 10,180,000 square kilometres, or 2% of the Earths surface, politically, Europe is divided into about fifty sovereign states of which the Russian Federation is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Europe had a population of about 740 million as of 2015. Further from the sea, seasonal differences are more noticeable than close to the coast, Europe, in particular ancient Greece, was the birthplace of Western civilization. The fall of the Western Roman Empire, during the period, marked the end of ancient history. Renaissance humanism, exploration, art, and science led to the modern era, from the Age of Discovery onwards, Europe played a predominant role in global affairs. Between the 16th and 20th centuries, European powers controlled at times the Americas, most of Africa, Oceania. The Industrial Revolution, which began in Great Britain at the end of the 18th century, gave rise to economic, cultural, and social change in Western Europe. During the Cold War, Europe was divided along the Iron Curtain between NATO in the west and the Warsaw Pact in the east, until the revolutions of 1989 and fall of the Berlin Wall. In 1955, the Council of Europe was formed following a speech by Sir Winston Churchill and it includes all states except for Belarus, Kazakhstan and Vatican City. Further European integration by some states led to the formation of the European Union, the EU originated in Western Europe but has been expanding eastward since the fall of the Soviet Union in 1991. The European Anthem is Ode to Joy and states celebrate peace, in classical Greek mythology, Europa is the name of either a Phoenician princess or of a queen of Crete. The name contains the elements εὐρύς, wide, broad and ὤψ eye, broad has been an epithet of Earth herself in the reconstructed Proto-Indo-European religion and the poetry devoted to it. For the second part also the divine attributes of grey-eyed Athena or ox-eyed Hera. The same naming motive according to cartographic convention appears in Greek Ανατολή, Martin Litchfield West stated that phonologically, the match between Europas name and any form of the Semitic word is very poor. Next to these there is also a Proto-Indo-European root *h1regʷos, meaning darkness. Most major world languages use words derived from Eurṓpē or Europa to refer to the continent, in some Turkic languages the originally Persian name Frangistan is used casually in referring to much of Europe, besides official names such as Avrupa or Evropa

Seed
–
A seed is an embryonic plant enclosed in a protective outer covering. The formation of the seed is part of the process of reproduction in seed plants, Seeds are the product of the ripened ovule, after fertilization by pollen and some growth within the mother plant. The embryo is developed from the zygote and the coat from the integuments of the ovule. Seed plants now dominate biological niches on land, from forests to both in hot and cold climates. The term seed also has a meaning that antedates the above—anything that can be sown, e. g. seed potatoes. In the case of sunflower and corn seeds, what is sown is the seed enclosed in a shell or husk, many structures commonly referred to as seeds are actually dry fruits. Plants producing berries are called baccate, sunflower seeds are sometimes sold commercially while still enclosed within the hard wall of the fruit, which must be split open to reach the seed. Different groups of plants have other modifications, the stone fruits have a hardened fruit layer fused to. Nuts are the one-seeded, hard-shelled fruit of plants with an indehiscent seed. Seeds are produced in several related groups of plants, and their manner of production distinguishes the angiosperms from the gymnosperms, angiosperm seeds are produced in a hard or fleshy structure called a fruit that encloses the seeds, hence the name. Some fruits have layers of hard and fleshy material. In gymnosperms, no special structure develops to enclose the seeds, however, the seeds do become covered by the cone scales as they develop in some species of conifer. Seed production in natural plant populations varies widely from year-to-year in response to weather variables, insects and diseases, over a 20-year period, for example, forests composed of loblolly pine and shortleaf pine produced from 0 to nearly 5 million sound pine seeds per hectare. Over this period, there were six bumper, five poor, and nine good seed crops, right after fertilization, the zygote is mostly inactive, but the primary endosperm divides rapidly to form the endosperm tissue. This tissue becomes the food the young plant will consume until the roots have developed after germination, after fertilization the ovules develop into the seeds. The ovule consists of a number of components, The funicle or seed stalk which attaches the ovule to the placenta and hence ovary or fruit wall, the nucellus, the remnant of the megasporangium and main region of the ovule where the megagametophyte develops. The micropyle, a pore or opening in the apex of the integument of the ovule where the pollen tube usually enters during the process of fertilization. The chalaza, the base of the ovule opposite the micropyle, the shape of the ovules as they develop often affects the final shape of the seeds

Root
–
In vascular plants, the root is the organ of a plant that typically lies below the surface of the soil. Roots can also be aerial or aerating, that is growing up above the ground or especially above water, furthermore, a stem normally occurring below ground is not exceptional either. Therefore, the root is best defined as the non-leaf, non-nodes bearing parts of the plants body, however, important internal structural differences between stems and roots exist. The fossil record of roots – or rather, infilled voids where roots rotted after death – spans back to the late Silurian and their identification is difficult, because casts and molds of roots are so similar in appearance to animal burrows. They can be discriminated using a range of features, the first root that comes from a plant is called the radicle. In response to the concentration of nutrients, roots also synthesise cytokinin, Roots often function in storage of food and nutrients. The roots of most vascular plant species enter into symbiosis with fungi to form mycorrhizae. In its simplest form, the root architecture refers to the spatial configuration of a plant’s root system. This system can be complex and is dependent upon multiple factors such as the species of the plant itself, the composition of the soil. The configuration of root systems serves to support the plant, compete with other plants. Roots grow to specific conditions, which, if changed, can impede a plants growth. For example, a system that has developed in dry soil may not be as efficient in flooded soil, yet plants are able to adapt to other changes in the environment. Root architecture plays the important role of providing a supply of nutrients and water as well as anchorage. The main terms used to classify the architecture of a system are, Branch magnitude. Root angle, the angle of a lateral root’s base around the parent root’s circumference, the angle of a lateral root from its parent root. Link radius, the diameter of a root, all components of the root architecture are regulated through a complex interaction between genetic responses and responses due to environmental stimuli. These developmental stimuli are categorised as intrinsic, the genetic and nutritional influences, or extrinsic, the main hormones and respective pathways responsible for root architecture development include, Auxin – Auxin promotes root initiation, root emergence and primary root elongation. Cytokinins – Cytokinins regulate root apical meristem size and promote lateral root elongation, gibberellins – Together with ethylene they promote crown primordia growth and elongation
