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:
“He said,
consider the flower of the field;
did he specify
blue or red?”
—Hilda Doolittle (1886–1961)
“So the soul, that drop, that ray
Of the clear fountain of eternal day,
Could it within the human flower be seen,
Remembering still its former height,
Shuns the sweet leaves and blossoms green;
And, recollecting its own light,
Does, in its pure and circling thoughts, express
The greater heaven in an heaven less.”
—Andrew Marvell (1621–1678)
“But the flower leaned aside
And thought of naught to say,
And morning found the breeze
A hundred miles away.”
—Robert Frost (1874–1963)
