Mitosis and meiosis are both processes of cell division, but they differ in the number of times a cell divides and the number of cells that result from each division. In mitosis, a single cell divides once, producing two identical daughter cells that contain the same genetic material as the parent cell. This type of cell division is used for growth and repair in multicellular organisms. In meiosis, a single cell divides twice, producing four daughter cells that have half the number of chromosomes as the parent cell. This type of cell division is used for sexual reproduction in multicellular organisms.
