Question

How many meiotic divisions are required to produce $1000$ pollen grains?

• A. $200$
• B. $250$
• C. $500$
• D. $1000$

Answer 1

The correct option is B $250$

Production of 4 haploid daughter cells from a single diploid mother cell is known as Meiosis Cell Division. Pollen grains are formed from Megaspore Mother Cell and each pollen grain contains one haploid gamete nucleus.

So, 4 pollen grains are produced by 1 meiosis

Therefore, 1000 pollen grains are produced by 1000/4 = 250 meiosis.

So, the correct option is B.
