NettetFormation of Female gametophyte (embryo sac): – In majority of flowering plants, one megaspore is functional while the other three degenerates. – he functional megaspore develops into the female gametophyte. The embryo sac formation from a single megaspore is called monosporic development. NettetThe female gametophyte — specifically termed a megagametophyte — is also called the embryo sac in angiosperms. The megagametophyte produces an egg cell for the purpose of fertilization. The ovule is a small structure present in the ovary. It is attached to the placenta by a stalk called a funicle. The funicle provides nourishment to the ovule.
