| What chromosome set is typical for sperm and pollen grain cells of pine seed. Explain from which initial cells and as a result of what division these cells are formed
1. Sperm — n, in the cells of the pollen grain — n. 2. Sperm are formed from cells of the pollen grain (generative cell) as a result of mitosis. 3. Pine pollen grain cells develop from haploid spores by mitosis.
