Question

How many mitosis and meiosis are required
for the formation of mature male
gametophyte from PMC :-

1) 1 meiosis, 2 mitosis
2) 3 mitosis, 1 meiosis
3) 2 meiosis, 2 mitosis
4) mitosis, 1 meiosis​

Answer 1

Answer:

After pollination, the generative cell after entering into the pollen tube divide mitotically to form two non-motile male gametes. Hence, 1 meiotic division and 2 mitotic division are required for the formation of fully mature male gametophyte from microspore mother cell in angiosperm.

Answer 2

2 meiosis and 1 mitosis are required for the formation of mature male gametophyte from PMC.
