The female gametophyte or the embryo sac develops from a single functional megaspore. This is known as monosporic development of the female gametophyte. In most flowering plants, a single megaspore mother cell present at the micropylar pole of the nucellus region of the ovule undergoes meiosis to produce four haploid megaspores. Later, out of these four megaspores, only one functional megaspore develops into the female gametophyte, while the remaining three degenerate.

The formation of female gametophyte or embryo sac from a single functional megaspore is called monosporic. The nucleus of functional megaspore undergoes 3 successive mitotic divisions to form haploid nuclei.
