Flower

A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) or allow selfing (fusion of sperm and egg from the same flower). Some flowers produce diaspores without fertilization (parthenocarpy). Flowers contain sporangia and are the site where gametophytes develop. Flowers give rise to fruit and seeds. Many flowers have evolved to be attractive to animals, so as to cause them to be vectors for the transfer of pollen.

In addition to facilitating the reproduction of flowering plants, flowers have long been admired and used by humans to beautify their environment, and also as objects of romance, ritual, religion, medicine and as a source of food.

Famous quotes containing the word flower:

    Criticism, that fine flower of personal expression in the garden of letters.
    Joseph Conrad (1857–1924)

    The intellectual is a middle-class product; if he is not born into the class he must soon insert himself into it, in order to exist. He is the fine nervous flower of the bourgeoisie.
    Louise Bogan (1897–1970)

    The country is holy: O bide in that country kind,
    Know the green good,
    Under the prayer wheeling moon in the rosy wood
    Be shielded by chant and flower and gay may you
    Lie in grace.
    Dylan Thomas (1914–1953)
