mitosis
Diploid Example:
__________
16 Chromosomes: divides by 2 = 2 new with 16 chromosomes each
Mitosis
Haploid Example:
__________ -
Spirogyra n=12

Haploid Example:
Only diploid cells can go through __________
meiosis
End Result:
__________-
Makes 4 nuclei from one nucleus each with half the number of chromosomes as the original
meiosis
End Result:
__________-
Makes 2 new nuclei from 1 nucleus, containing the same number of chromosomes as the original
