Question

How many meiotic divisions are required to produce 200 seeds?

• A. 50
• B. 100
• C. 200
• D. 250

Answer 1

The correct option is D 250

Meiotic division in female plants forms three cells, of which one forms the egg cell and the remaining 3 degenerates to provide nutrition to the developing egg cell. So, 200 meiotic divisions will give 200 egg cells. And in the male gametophyte, each meiotic division leads to the formation of 4 male gametes. So, 50 meiotic divisions in the male gametophyte will lead to the formation of 200 male gametes. So, the total number of meiotic divisions required to form 200 zygotes = 250. Each zygote will lead to the formation of one seed. So, the correct option is '250'.
