Question

The minimum number of meiotic divisions required to obtain 100 pollen grains of wheat is

• A. 25
• B. 50
• C. 100
• D. 150

Answer 1

The correct option is A 25

During sexual reproduction in angiosperms, meiosis occurs in microspore and megaspore mother cells. In one meiotic division, one microspore mother cell in the anther forms 4 microspores, each of which develops as a pollen grain. When there are 100 pollen grains, the meiotic divisions which will be required are 100/4= 25. The number of meiotic divisions for 100 pollen grains is 25.

Thus, the correct answer is option A.
