The correct answer is: C. Meiosis
Meiosis is a type of cell division that results in four daughter cells each with half the number of chromosomes as the parent cell. This process is essential for sexual reproduction, as it allows for the production of gametes (sperm and eggs) with half the number of chromosomes as the parent organism.
Mitosis is a type of cell division that results in two daughter cells each with the same number of chromosomes as the parent cell. This process is responsible for the growth and repair of tissues in the body.
Pollination is the transfer of pollen from the male part of a flower (the stamen) to the female part of a flower (the pistil). This process is necessary for fertilization, which is the fusion of the male and female gametes to produce a seed.
Fertilization is the fusion of the male and female gametes to produce a zygote. The zygote then divides and develops into an embryo, which eventually becomes a new plant.
In conclusion, pollen is produced by the process of meiosis. This process is essential for sexual reproduction, as it allows for the production of gametes (sperm and eggs) with half the number of chromosomes as the parent organism.
