Question

How many pollen grains and ovules are likely to be formed in the anther and the ovary of an angiosperm bearing 50 microspore mother cells and 50 megaspore mother cells respectively?

पर्याय

• 100, 25

• 200, 50

• 50, 50

• 200, 100

Answer 1

200, 50

Explanation:

After going through meiosis, each microspore mother cell (MMC) produces four pollen grains. Thus, 200 pollen grains = 50 MMCs. Only one of the four megaspores produced by each megaspore mother cell (MMC) develops into an ovule. Thus, 50 ovules = 50 MMCs.
