The flower produces two kinds of gametophytes, male and female. The female gametophyte arises from a cell within theovule, a small structure within the ovary of the flower. The ovary is a larger structure within the flower that contains and protects usually many ovules. Flowering plants are un...
The pistil, made up of the basal ovary that bears the ovules, elongated style, and terminal stigma, is the female reproductive organ of the flower. The female gametophyte, designated as the embryo sac, is located inside the ovule. The pistil is the recipient of the pollen and a conduit ...
The male reproductive parts of the flower include the anther and filament. These two structures make up the stamen. In contrast, the female reproductive parts of the flower include the stigma, style, and ovary. These three parts make up the pistil. Stamen and pistil diagram The process of po...
