Information: - South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It is also considered a subcontinent of the Americas, which is the model used in nations that speak Romance languages. The reference to South America instead of other regions (like Latin America or the Southern Cone) has increased in the last decades due to changing geopolitical dynamics (in particular, the rise of Brazil). - A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown. These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external ambient temperature, protecting its contents in cold weather. - In everyday usage, a vegetable is any part of a plant that is consumed by humans as food as part of a savory meal. The term "vegetable" is somewhat arbitrary, and largely defined through culinary and cultural tradition. It normally excludes other food derived from plants such as fruits, nuts, and cereal grains, but includes seeds such as pulses. The original meaning of the word "vegetable", still used in biology, was to describe all types of plant, as in the terms "vegetable kingdom" and "vegetable matter". - The Colonial expansion under the crown of Castile was initiated by the Spanish "conquistadores" and developed by its administrators and missionaries. The motivations for colonial expansion were trade and the spread of the Catholic faith through indigenous conversions. - The tomato (see pronunciation) is the edible fruit of "Solanum lycopersicum", commonly known as a tomato plant, which belongs to the nightshade family, "Solanaceae". The species originated in Central and South America. The Nahuatl (Aztec language) word "tomatl" gave rise to the Spanish word "tomate", from which the English word tomato originates. Numerous varieties of tomato are widely grown in temperate climates across the world, with greenhouses allowing its production throughout the year and in cooler areas. The plants typically grow to in height and have a weak stem that often sprawls over the ground and vines over other plants. It is a perennial in its native habitat, and grown as an annual in temperate climates. An average common tomato weighs approximately . Its use as a food originated in Mexico, and spread throughout the world following the Spanish colonization of the Americas. Tomato is consumed in diverse ways, including raw, as an ingredient in many dishes, sauces, salads, and drinks. While tomatoes are botanically berry-type fruits, they are considered culinary vegetables, being ingredients of savory meals. - In botany, a fruit is the seed-bearing structure in flowering plants (also known as angiosperms) formed from the ovary after flowering. - Solanum is a large and diverse genus of flowering plants, which include two food crops of high economic importance, the potato and the tomato. It also contains the nightshades and horse nettles, as well as numerous plants cultivated for their ornamental flowers and fruit. - An heirloom tomato ( also called heritage tomato in the UK ) is an open - pollinated ( non-hybrid ) heirloom cultivar of tomato . Heirloom tomatoes have become increasingly popular and more readily available in recent years . According to tomato experts Craig LeHoullier and Carolyn Male , heirloom tomatoes can be classified into four categories : family heirlooms , commercial heirlooms , mystery heirlooms , and created heirlooms . They are grown for a variety of reasons , such as historical interest , access to wider varieties , and by people who wish to save seeds from year to year , as well as for their taste , which is widely perceived to be better than modern tomatoes . They usually have a shorter shelf life , but are generally more disease resistant than most commercial tomatoes , except for specific disease ( s ) , for which a commercial hybrid was bred to be resistant . Furthermore , some scientists have suggested that heirloom tomatoes are no more natural than commercial ones , and that many are simply '' inbred '' tomatoes . - The Aztec people were certain ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl language and who dominated large parts of Mesoamerica from the 14th to 16th centuries. The Nahuatl words "aztecatl" (singular) and "aztecah" (plural) mean "people from Aztlan", a mythological place for the Nahuatl-speaking culture of the time, and later adopted as the word to define the Mexica people. Often the term "Aztec" refers exclusively to the Mexica people of Tenochtitlan (now the location of Mexico City), situated on an island in Lake Texcoco, who referred to themselves as "Mxihcah Tenochcah" or "Clhuah Mexihcah" . - Mexico (, modern Nahuatl ), 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 (over 760,000sqmi), Mexico is the sixth largest country in the Americas by total area and the 13th largest independent nation in the world. With an estimated population of over 120 million, it is the eleventh most populous country and the most populous Spanish-speaking country in the world while being the second most populous country in Latin America. 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 and Leon. - The term cultivar is, most commonly, referring to an assemblage of plants selected for desirable characteristics that are maintained during propagation. More generally, "cultivar" refers to the most basic classification category of cultivated plants governed by the ICNCP. Most cultivars have arisen in cultivation, but a few are special selections from the wild. - A drink or beverage is a liquid intended for human consumption. In addition to their basic function of satisfying thirst, drinks play important roles in human culture. Common types of drinks include plain water, milk, juices, coffee, tea, and soft drinks. In addition, alcoholic drinks such as wine, beer, and liquor, which contain the drug ethanol, have been part of human culture and development for 8,000 years. Given the paragraphs above, decide what entity has the relation 'instance of' with 'vegetable'.
The answer to this question is:
heirloom tomato
