How many pollen mother cells should undergo meiotic division to produce 64 pollen grains?

A

64

B

32

C

16

D

8

Text Solution

Verified by Experts

The correct Answer is:
C
Each pollen mother cell `(PMC)`, by a meiotic division, gives rise to a group of four haploid microspores. Thus, `16` pollen mother cells undergo meiotic divisions to produce 64 pollen grains.
