A flower, occasionally known as flower or flower, is the reproductive structure found in plants with flowers (plants of the Magnoliophyta division, also called angiosperms). The biological function of a flower is to effect reproduction, commonly providing a mechanism for joining sperm with eggs. Flowers can facilitate crossing (fusion of sperm and eggs of different individuals in a population) or allow self-sufficiency (fusion of sperm and eggs from the same flower). Some flowers produce diasporas without fertilization (parthenocarpy). The flowers contain sporangia and are the site of gametophytes. Many flowers have evolved to be attractive to animals, in order to make them vectors for pollen transfer. After fertilization, the ovary of flowers becomes fruit containing seeds.
In addition to facilitating the reproduction of plants with flowers, flowers have been admired and used by humans to bring beauty to their surroundings, and also as objects of romance, ritual, religion, medicine and as a food source.
A flower develops on a modified button or shaft from a particular apical meríde (a certain meaning that the axis grows to a defined size). It has tablets, having structures that in the morphology of classical plants are interpreted as highly modified leaves. Detailed development studies, however, have shown that stamens often begin more or less as modified stems (stems) that in some cases may even resemble branches. Taking into account all the diversity in the development of androecium of flowering plants, we find a continuum between the modified leaves (phylomas), modified stems (stems) and modified branches (shoots).
