The female gametophyteâspecifically termed a megagametophyte âis also called the embryo sac in angiosperms.

Ovules are attached to the placenta in the ovary through a stalk-like structure known as a funiculus (plural, funiculi).

Cone Function. Each coniferous tree produces both male and female cones. Male cones are much smaller and less showy than their female counterparts.
