Chromosomes of the male gametophyte

The chromosome number of a pollen mother cell is $2n$. You will work out the number in the cells of the male gametophyte and find which plant has the largest number.

The idea. Meiosis halves the number. The mitoses of the pollen grain keep it.

Your tasks.

1. Finish haploid. It gives the chromosomes in a microspore for a given $2n$.
2. Finish three_celled_total. It gives the chromosomes in all three nuclei of a three-celled pollen grain.
3. Set most to the name of the plant whose male gametes have the most chromosomes.
