Question

Describe the megaspore development in an angiospermic plant.

Prabhat Rajore · Accepted Answer

The Ovules generally have one megaspore mother cell at the micropylar end . The megaspore mother cell has dense cytoplasm and a prominent nucleus. It  undergoes meiosis  twice to form a linear tetrad of four haploid cells. Out of these foure cells one cell functions as the megaspore while the other three cells degenerate. Functional megaspore gives rise to female gametophyte.  - Wired Faculty
