Megasprogenesis The formation of megaspore mother cells from megaspore mother cells is called megasporogenesis. This process occurs inside the nucellus of developing ovule of angiosperms. It is surrounded by a layer known as the epidermis . Below the epidermis, there is a layer known as hypodermis. One cell of hypodermic divide and grow in a bigger size which is known as archesporial cells. These archesporial cells divide periclinal to form an outer parietal layer and inner sporogenous cells. These sporogenous cells function as megaspore mother cells (MMC). These cells divide meiotically and form four haploid tetrad cells. Out of which three degenerate and only one remain is functional.
