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 affect 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) resulting from
cross pollination or allow selfing (fusion of sperm and egg from the same flower) when self pollination occurs. Some
flowers produce diaspores without fertilization (parthenocarpy).
Flowers contain sporangia and are the site where gametophytes develop. Many
flowers have evolved to be attractive to
animals, so as to cause them to be vectors for the transfer of
pollen. After fertilization, the ovary of the flower develops into
fruit containing seeds.
In addition to facilitating the reproduction of flowering
plants,
flowers have long been admired and used by humans to bring
beauty to their environment, and also as objects of romance, ritual, religion,
medicine and as a source of food.
The essential parts of a flower can be considered in two parts: the vegetative part, consisting of petals and associated structures in the perianth, and the reproductive or sexual parts. A stereotypical flower consists of four kinds of structures attached to the tip of a short stalk.
