Male Gamete Formation

Question 1

Are the cells lining the inside of the anther diploid or haploid?

Answer 1

Diploid

Question 2

What cells in the anther are diploid?

Answer 2

The cells lining the inside of the anther

Question 3

Where exactly does meiosis occur during male gamete formation?

Answer 3

Meiosis takes place in some of the diploid cells lining the inside of the anther

Question 4

What is formed by meiosis in the diploid cells lining the inside of the anther?

Answer 4

Pollen grains are formed

Question 5

What do the pollen grains formed by meiosis contain?

Answer 5

A single haploid nucleus

Question 6

What happens to each pollen grain after they have been formed?

Answer 6

They divide by mitosis to form the make sex cells/male gamete nuclei/sperm nuclei

Question 7

What are the names of the structures formed from mitosis of the pollen grains?
(3)

Answer 7

Male sex cells

Male gamete nuclei

Sperm nuclei

Question 8

What happens when the pollen grains are fully developed?

Answer 8

The anther splits and peels back so that the pollen grains are exposed on the outside of the anther

Question 9

Why does the anther split and peel back when the pollen grains are fully developed?

Answer 9

So that the pollen grains are exposed on the outside of the anther
