Question

How does the megaspore mother cell divide in most angiosperms?

Answer 1

Megasporogenesis:

1. The development of megaspores from the megaspore mother cell is called megasporogenesis.
2. Megaspore mother cell is a large cell with dense cytoplasm and a differentiated nucleus.
3. In most angiosperms, the megaspore-mother cell divides through meiosis and forms 4 megaspores.
4. These megaspores are arranged linearly.
5. Three of these megaspores degenerate and only one is active.
6. Active megaspore forms female gametophyte.
