Hello student,

Microsporogenesis is defined as the formation of microspores from microspore mother cells by meiosis . It occurs inside the pollen sac of the anther.

Megasporogenesis is defined as the process of arrangement of megaspores from the megaspore mother cell. It occurs in the ovule of the ovary.

• Meiosis occurs in both the above cases.
• Structures formed at the end : Microsporogenesis results in haploid microspore forming from the diploid microspore mother cell while megasporogenesis results in haploid megaspore forming from the diploid megaspore mother cell.

Thank you and good luck.
