In angiosperms, microsporogenesis and megasporogenesis:
Open in App
Solution
The correct option is D involve meiosis
In angiosperms, microsporogenesis occurs inside the anther and megasporogenesis occurs inside the ovule.
Microsporogenesis involves the formation of haploid microspores from pollen mother cells (PMC) by meiotic division.
Microspores develop into pollen grains. The pollen grain undergoes mitotic divisions to form the male gametes.
Megasporogenesis is the process of formation of haploid megaspores from the megaspore mother cell by meiotic division. Out of the 4 megaspores formed, one remains functional and undergoes mitotic divisions to form the female gamete or egg.
Hence, option D is correct.
