If there are 10 megaspores mother cell. How many functional megaspores will be formed?
Megaspore Mother cell (2n) undergoes meiosis to form 4 haploid megaspores. Out of four megaspores one of the megaspores is functional while the other three degenerate.
1 Megaspore Mother cell forms 1 functional megaspores.
Therefore, 10 Megaspore Mother cell forms 10 functional megaspores.
