Question

which process could occur in maple trees to decrease the chromosome number in pollen cells from 52 down to 26?

• binary fission
• meiosis
• mitosis
• vegetative propagation

Explanation:

Meiosis is a type of cell - division that reduces the chromosome number by half. It occurs in the formation of gametes (such as pollen cells in plants). Mitosis results in daughter cells with the same chromosome number as the parent cell. Binary fission is a form of asexual reproduction in prokaryotes and some single - celled eukaryotes. Vegetative propagation is a form of asexual reproduction in plants that does not involve a reduction in chromosome number.

Answer:

meiosis
