An anther has 1200 pollen grains. How many pollen mother cells must have been there to produce them?

Solution: One Pollen Mother Cell (PMC) produces four haploid pollen grains during meiosis. Thus, 1200/4=300 PMCs are required to produce 1200 pollen grains.

1 pollen mother cell →4 pollen grain. Therefore, no. of PMC = 1200/4 = 300 pollen grains.
