Question

If there are 4 cells in anthers, what will be the number of pollen grains?

• A. 16
• B. 12
• C. 8
• D. 4

Answer 1

The Correct Option is A

The question pertains to the biology of plant reproduction, specifically regarding the process by which pollen grains are formed in angiosperms (flowering plants).

The fertilization process in plants involves the male gametes, which are produced in the pollen grains. These pollen grains originate from a structure known as the microsporangium found within the anther of a flower.

Let's solve the problem step-by-step:

1. Each cell in the anther is a diploid pollen mother cell (microsporocyte).
2. A pollen mother cell undergoes meiosis, a type of cell division that reduces the chromosome number by half, resulting in four haploid cells from each diploid microsporocyte.
3. These four cells are called microspores, each forming a pollen grain.
4. Therefore, if there are 4 pollen mother cells in the anther, they will undergo meiosis to produce a total of: 4 \times 4 = 16 pollen grains.

Given the calculations above, the correct answer is 16 pollen grains.

Therefore, the correct option is 16.
