Question

how many pollen grains and ovules are likely to be formed in the anther and the ovary of an angiosperm bearing 25 microscope mother cells and 25 megaspore mother cells respectively

Answer 1

100 Pollen grains and 25 Ovules.

SEE 1 microspore mother cell through mitosis produces 4 pollen grains

so 25 microspore mother cell will produce 100 pollen grains.

1 megaspore mother cell too produces 4 megaspores out of which in majority of flowering plants 3 megaspores degenrate......so only one remains.

so 25 megaspore mother cell produces 25 ovules.
