Question

During development of male gametophyte from pollen mother cell, there occurs

• A. Two meiotic divisions and one mitotic division
• B. Two mitotic divisions
• C. One meiotic and two mitotic divisions
• D. One meiotic cell division and one mitotic cell division

Answer 1

The correct option is C One meiotic and two mitotic divisions

During microsporogenesis, microsporocytes undergo-
1) One meiotic division : to produce a tetrad of four haploid microspores. The released microspores undergo a highly asymmetric division.
2) 1st Mitosis : to produce a bicellular pollen grain with a small germ cell engulfed within the cytoplasm of a large vegetative cell. The germ cell undergoes a further mitotic division.
3) 2nd Mitosis : to produce twin sperm cells.

So the correct answer is option C i.e. 'One meiotic and two mitotic divisions'.
