The reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms is a flower that is also known as a bloom or blossom. Effecting reproduction by providing a mechanism for the union of sperm with eggs is the biological function of a flower. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) which results in from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are also some unique flowers that produce diaspores without fertilization (parthenocarpy).
Flowers have sporangia which are the site where gametophytes develop. Animals become vectors for the transfer of pollen as many flowers have evolved to be attractive to animals. The ovary of the flower develops into fruit containing seeds After fertilization.
