Hook
A hook is a tool consisting of a length of material, typically metal, that contains a portion that is curved or indented, such that it can be used to grab onto, connect, or otherwise attach itself onto another object. In a number of uses, one end of the hook is pointed, so that this end can pierce another material, which is then held by the curved or indented portion. Some kinds of hooks, particularly fish hooks, also have a barb, a backwards-pointed projection near the pointed end of the hook to ensure that once the hook is embedded in its target, it can not easily be removed. Variations * Bagging hook, a large sickle or reaping hook used for harvesting grain * Bondage hook, used in sexual bondage play * Cabin hook, a hooked bar that engages into an eye screw, used on doors * Cap hook, hat ornament of the 15th and 16th centuries * Cargo hook (helicopter), different types of hook systems for helicopters * Crochet hook, used for crocheting thread or yarn * Drapery hook, for ha ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ...

Simaroubaceae
The Simaroubaceae are a small, mostly tropical, family in the order Sapindales. In recent decades, it has been subject to much taxonomic debate, with several small families being split off. A molecular phylogeny of the family was published in 2007, greatly clarifying relationships within the family. Together with chemical characteristics such as the occurrence of petroselinic acid in ''Picrasma'', in contrast to other members of the family such as ''Ailanthus'', this indicates the existence of a subgroup in the family with ''Picrasma'', ''Holacantha'', and ''Castela''. The best-known species is the temperate Chinese tree-of-heaven ''Ailanthus altissima'', which has become a cosmopolitan weed tree of urban areas and wildlands. Well-known genera in the family include the tropical ''Quassia'' and ''Simarouba ''Simarouba'' is a genus of trees and shrubs in the family Simaroubaceae, native to the neotropics. It has been grouped in the subtribe Simaroubina along with the ''Simaba'' ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Dioecious
Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only about half the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. Dioecy is a dimorphic sexual system, alongside gynodioecy and androdioecy. In zoology In zoology, dioecious species may be opposed to hermaphroditic species, meaning that an individual is either male or female, in which case the synonym gonochory is more often used. Most animal species are dioecious (gon ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sapindales Genera
Sapindales is an order of flowering plants. Well-known members of Sapindales include citrus; maples, horse-chestnuts, lychees and rambutans; mangos and cashews; frankincense and myrrh; mahogany and neem. The APG III system of 2009 includes it in the clade malvids (in rosids, in eudicots) with the following nine families: *Anacardiaceae *Biebersteiniaceae *Burseraceae *Kirkiaceae *Meliaceae *Nitrariaceae (including Peganaceae and Tetradiclidaceae) *Rutaceae *Sapindaceae *Simaroubaceae The APG II system of 2003 allowed the optional segregation of families now included in the Nitrariaceae. In the classification system of Dahlgren the Rutaceae were placed in the order Rutales, in the superorder Rutiflorae (also called Rutanae). The Cronquist system of 1981 used a somewhat different circumscription, including the following families: *Staphyleaceae *Melianthaceae * Bretschneideraceae *Akaniaceae *Sapindaceae *Hippocastanaceae *Aceraceae *Burseraceae *Anacardiaceae *Julianiaceae ...
