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)
“and men strive with each other not for power or the accumulation of paper
but in joy create for others the house, the poem, the game of
athletic beauty.
Then washed in the brightness of the vision,
I saw how in its radiance would grow and be nourished and suddenly
burst into terrible and splendid bloom
the blood-red flower of revolution.”
—Dudley Randall (b. 1914)
“Slavery and servility have produced no sweet-scented flower annually, to charm the senses of men, for they have no real life: they are merely a decaying and a death, offensive to all healthy nostrils. We do not complain that they live, but that they do not get buried. Let the living bury them; even they are good for manure.”
—Henry David Thoreau (1817–1862)
