Quizplus · Accepted Answer

Meiosis is the process of cell division that occurs in the testes of men and ovaries of women. During meiosis, the cell duplicates its chromosomes and then divides twice, resulting in the formation of four cells, each with only half the genetic material of the parent cell. This is necessary for the formation of gametes (sperm and eggs) that contain a unique combination of genetic material from both parents during fertilization. Mitosis, on the other hand, is the process of cell division that occurs in somatic (non-reproductive) cells and results in the formation of two identical daughter cells. Osmosis is the diffusion of water molecules across a selectively permeable membrane. Fertilization is the fusion of gametes to form a zygote.
