Question

In the following case mention the correct ratio of pollen mother cells, generative cells, vegetative cells, and male gametes produced by the microsporangium.

A total of 168 pollen grains with 14 chromosomes in each pollen grain are released from a mature microsporangium.

Options

• 9:3:3:4

• 1:2:1:4

• 1:4:4:8

• 1:1:1:4

Answer 1

1:4:4:8

Explanation:

There are 168 pollen grains in total. As a result, the number of pollen mother cells is 168/4=42. One vegetative cell and one generative cell are found in each pollen grain. As a result, there are 168 total vegetative cells and 168 total generative cells. Mitosis occurs in each generative cell, resulting in the formation of two male gametes. As a result, 336 male gametes will be created from 168 pollen grains. As a result, the correct.
