Question

How many meiotic divisions occur to produce 100 pollen grains?

Answer 1

Answer:

To produce 100 pollen grain there coccur 25 meiotic divison

Explanation:

Because one meiotic divison produce 4 pollen grain.So 25 ×4=100

And there also occur 100 mitotic divison

Answer 2

Answer:

Since your question is pollen grains, the answer = 25

Explanation:

100 egg cells = 100 meiotic division

100 egg cells = 100 meiotic division 100 pollen grains = 100/4 = 25 meiotic

100 egg cells = 100 meiotic division 100 pollen grains = 100/4 = 25 meiotic divisions.

100 egg cells = 100 meiotic division 100 pollen grains = 100/4 = 25 meiotic divisions.To form 100 zygotes;

100 egg cells = 100 meiotic division 100 pollen grains = 100/4 = 25 meiotic divisions.To form 100 zygotes;Total no.of meiotic division = 100 + 25 = 125.
