Which of the following is correct ?

Easy

A

In about 70% of angiosperms, pollination occur at 3-celled stage.
B

In about 40% of angiosperms, pollination occur at 2-celled stage.
C

Generative cell divides meiotically to form two male gametes.
D

In about 60% of the angiosperms, pollination occur when a pollen grain at least forms a vegetative cell and a generative cell.

Solution

In over 60% of angiosperms, pollen grains are shed at 2 celled stage. In the remaining species the generative cell divides mitotically to give rise to the two male gametes before pollen grains are shed ( 3 celled stage).
