Solution

Microsporogensis involves meiosis in microspore/pollen mother cells to produce microspores/pollen grains tetrads that remain suspended in central of each microsporangium. Pollen mother cells are present in each microsporangium of anther.
Megasporogenesis includes meiosis in megaspore mother cell of ovule to form megaspore tetrad out of which one megapore is functional.
Meiosis occurs during both megasporogenesis and microsporogenesis to prodduce haploid male and female gametes. Microsporogenesis forms haploid microspores while megasporogenesis forms haploid megaspores.
