How many pollen grains and ovules are likely to be formed in the anther and ovary of an angiosperm bearing - Biology - Sexual Reproduction in Flowering Plants

Question

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

Each MMC (microspore mother cell) gives rise to four micropores
each of which develops into male gametophyte (pollen grain) So,
number of pollen grains likely to be formed in anther with total of
25 MMC are 100 (25 x 4)

Each megaspore mother cell gives rise to four megaspores , out of
which three degenerate and only one functional megapsore develops
into ovule So, number of ovules likely to be formed in ovary with
total of 25 MMC are 25 (25 x 1)
