An oak is a tree A tree is a perennial woody plant. It is most often defined as a woody plant that has many secondary branches supported clear of the ground on a single main stem or trunk with clear apical dominance. A minimum height specification at maturity is cited by some authors, varying from 3 m to 6 m; some authors set a minimum of 10 cm trunk diameter or shrub A shrub or bush is a horticultural rather than a strict botanical category of woody plant, distinguished from a tree by its multiple stems and lower height, usually less than 5–6 m tall. A large number of plants can be either shrubs or trees, depending on the growing conditions they experience. Small, low shrubs such as lavender, periwinkle and in the genus In biology, a genus is a taxonomic unit (a taxon) used in the classification of living and fossil organisms. The term comes from Latin genus "descent, family, type, gender", cognate with Greek: γένος – genos, "race, stock, kin" Quercus (pronounced /ˈkwɜrkəs/;[1] Latin Latin is an Italic language originally spoken in Latium and Ancient Rome. With the Roman conquest, Latin was spread to countries around the Mediterranean, including a large part of Europe. Romance languages, such as Catalan, French, Italian, Portuguese, Romanian, and Spanish, are descended from Latin, while many others, especially European "oak tree"), of which about 400 species This is an incomplete list of Quercus species. The genus contains about 400 species exist on earth. "Oak" may also appear in the names of species in related genera, notably Lithocarpus Lithocarpus is a genus in the beech family Fagaceae, differing from Quercus in the erect male spikes. The Kew Checklist accepts 334 species, though some other texts suggest as low as 100 species. About 100 Asian species of the genus were formerly treated in the genus Pasania. All but one are native to east and southeast Asia; the single exception,. The genus is native to the northern hemisphere The Northern Hemisphere is the half of a planet that is north of the equator—the word hemisphere literally means 'half sphere'. It is also that half of the celestial sphere north of the celestial equator. Earth's northern hemisphere contains most of its land area and most of its human population, and includes deciduous Deciduous means falling off at maturity or tending to fall off and is typically used in reference to trees or shrubs that lose their leaves seasonally and to the shedding of other plant structures such as petals after flowering or fruit when ripe. In a more specific sense deciduous means the dropping of a part that is no longer needed, or falling and evergreen In botany, an evergreen plant is a plant having leaves all year round. This contrasts with deciduous plants, which completely lose their foliage for part of the year species extending from cold latitudes to tropical The tropics, seated in the equatorial regions of the world, are limited in latitude by the Tropic of Cancer in the northern hemisphere at approximately 23°26' N latitude and the Tropic of Capricorn in the southern hemisphere at 23°26' (23.4°) S latitude. The tropics are also referred to as the tropical zone and the torrid zone (see geographical Asia Asia is the world's largest and most populous continent, located in the eastern and northern hemispheres. It covers 8.6% of the earth's total surface area and with approximately 4 billion people, it hosts 60% of the world's current human population and the Americas The Americas, or America, are the lands of the Western hemisphere or New World, comprising the continents of North America and South America with their associated islands and regions. America may be ambiguous in English, as it is more commonly used to refer to the United States of America. The Americas cover 8.3% of the Earth's total surface area.
Oaks have spirally arranged leaves In botany, a leaf is an above-ground plant organ specialized for photosynthesis. For this purpose, a leaf is typically flat and thin. There is continued debate about whether the flatness of leaves evolved to expose the chloroplasts to more light or to increase the absorption of carbon dioxide. In either case, the adaption was made at the expense, with a lobed margin in many species; some have serrated leaves or entire leaves with a smooth margin. The flowers A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants . The biological function of a flower is to mediate the union of male sperm with female ovum in order to produce seeds. The process begins with pollination, is followed by fertilization, leading to the formation and dispersal of the seeds. For are catkins A catkin or ament is a slim, cylindrical flower cluster, with inconspicuous or no petals, usually wind-pollinated but sometimes insect pollinated (as in Salix). They contain many, usually unisexual flowers, arranged closely along a central stem which is often drooping. They are found in many plant families, including Betulaceae, Fagaceae, Moraceae,, produced in spring. The fruit The term fruit has different meanings dependent on context, and the term is not synonymous in food preparation and biology. Fruits are the means by which flowering plants disseminate seeds, and the presence of seeds indicates that a structure is most likely a fruit, though not all seeds come from fruits is a nut Nut is a hard shelled fruit of some plants that has an indehiscent seed. While a wide variety of dried seeds and fruits are called nuts in English, only a certain number of them are considered by biologists to be true nuts. Nuts are an important source of nutrients for both humans and wildlife called an acorn The acorn, or oak nut, is the nut of the oak tree . It usually contains a single seed (rarely two seeds), enclosed in a tough, leathery shell, and borne in a cup-shaped cupule. Acorns vary from 1–6 cm long and 0.8–4 cm broad. Acorns take between about 6 or 24 months (depending on the species) to mature; see List of Quercus species for details, borne in a cup-like structure known as a cupule The calybium and the cupule make up the accessory fruit of flowering plants in the family Fagaceae. These two parts derive from different flower components; each acorn contains one seed (rarely two or three) and takes 6–18 months to mature, depending on species. The live oaks Live oak or evergreen oak is a general term for a number of unrelated oaks in several different sections of the genus Quercus that happen to share the characteristic of evergreen foliage are distinguished for being evergreen In botany, an evergreen plant is a plant having leaves all year round. This contrasts with deciduous plants, which completely lose their foliage for part of the year, but are not actually a distinct group and instead are dispersed across the genus.
