Les fleurs

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 facilitate 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.

La flor es la estructura reproductiva característica de las plantas llamadas espermatofitas o fanerógamas. La función de una flor es producir semillas a través de la reproducción sexual. Para las plantas, las semillas son la próxima generación y sirven como el principal medio a través del cual las especies se perpetúan y se propagan.
