WebApr 4, 2024 · Meiosis is the process of cell division in which a single cell divides to form four genetically different daughter cells. It occurs in gametes (sperm and egg cells). Somatic cells and germ cells follow different processes of cell division. The phases of mitosis and meiosis are the same, but the resulting cells are different. WebCell division is the process by which cells can make more cells. It only allows organisms to become more complex, it also allows organisms to replace cells and repair tissue.
