1
Q

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

A

Diploid

2
Q

What cells in the anther are diploid?

A

The cells lining the inside of the anther

3
Q

Where exactly does meiosis occur during male gamete formation?

A

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

4
Q

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

A

Pollen grains are formed

5
Q

What do the pollen grains formed by meiosis contain?

A

A single haploid nucleus

6
Q

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

A

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

7
Q

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

A

Male sex cells

Male gamete nuclei

Sperm nuclei

8
Q

What happens when the pollen grains are fully developed?

A

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

9
Q

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

A

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