What chromosome set is typical for the cells of the pollen grain and sperm cells of the pine? Explain from which initial cells and as a result of what division these cells are formed.

1. The cells of the pollen grain have a haploid set of chromosomes (n), since it is formed from a haploid microspore (n) by mitosis. 2. The sperm has a haploid set of chromosomes (n), since they are formed from a generative cell of a pollen grain with a haploid set of chromosomes (n) by mitosis.
