plants from different familiesA 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.
