angiosperm life cycle
Figure 16: Typical angiosperm life cycle (see text).
A megasporocyte is a megaspore mother cell. In plants, specifically angiosperms, the megasporocyte is a large cell that arises within the nucellus near the micropyle. This cell undergoes meiotic division to produce a linear tetrad of megaspores. Typically, three of these megaspores degenerate, and the surviving one enlarges to form the megagametophyte, which then produces the female gametes, or eggs. This process is a crucial part of sexual reproduction in plants.12
