Question

Which among the following is the correct developmental sequence during microsporogenesis?

• A. Pollen grain - microspore tetrad- pollen mother cell- male gametes
• B. Male gametes - pollen mother cell - pollen grain - microspore tetrad
• C. Microspore tetrad - pollen mother cell - male gametes - pollen grain
• D. Pollen mother cell - microspore tetrad - pollen grain - male gametes

Answer 1

The correct option is D Pollen mother cell - microspore tetrad - pollen grain - male gametes

The correct developmental sequence during microsporogenesis is pollen mother cell - microspore tetrad - pollen grain - male gametes.
The pollen mother cell (PMC) undergoes meiosis and forms haploid microspore tetrad.
The microspores develop into pollen grains.
Pollen grains divide mitotically and form a vegetative and a generative cell.
The generative cell undergoes mitosis and forms two male gametes.
