Solution

The correct option is D Sporogenous tissue pollen mother cell microspore pollen grain
The male reproductive organ in a flower is called stamen. It consists of a stalk called the filament and the terminal bilobed structure called the anther.

A young anther contains specialised cells called sporogenous cells. These cells form microspore mother cells inside a sac-like structure called microsporangium.

Microspore mother cells undergo meiosis to form microspores (4). Microspores then absorb nutrition and undergo further development to form pollen grains.

The pollen grains consist of vegetative and generative cells. The generative cells give rise to the male gametes in the pollen grain while the vegetative cell gives rise to the pollen tube.

Hence, the correct order is:
Sporogenous tissue pollen mother cell microspore pollen grain.
