Text Solution

Verified by Experts

The correct Answer is:
A
The wall of the pollen mother cell (microspore mother cell) is deposited by callose (`beta`-1, 3-glucan). Callose plays a significant role in reproductive biology of angiosperms. It acts as a temporary wall to prevent the product of meiosis from cohesion and fusion and its dissolution results in the release of free spores.
