Answer 1

Answer:

which standard do yoi are

Answer 2

Answer:

25 meiotic divisions

Explanation:

Pollen grains (microspores) are produced in the anther. The anther has 4 lobes, each representing a micro-sporangium . Cells of sporogenous tissue in micro-sporangium function as microspore mother cells. Each microspore mother cell undergoes meiosis to form 4 haploid micropores. Each microspore (pollen grain ) develops into male gametophyte that produces male gamete.

Thus one meiotic division produces 4 micropores and consequently 4 male gametes.
