Megaspore mother cell
From Wikipedia, the free encyclopedia
A megaspore mother cell is a diploid cell in which meiosis will occur, resulting in the production of four megaspores.[1] This megasporcyte is formed from two distinct processes – megasporogenesis and megagametogenesis.[2]
Within each sporangium, meiosis of a megaspore mother cell produces four haploid megaspores.[2] In gymnosperms and angiosperms, only one of these four megaspores is functional and the other three soon degenerate. The megaspore that remains divides mitotically and develops into the female gametophyte, which eventually produces eggs.[2]
