Cell division, or mitosis, is a vital process in the life cycle of all living organisms. It is the process by which a single cell divides into two identical daughter cells, each containing the same genetic material as the parent cell. During mitosis, the genetic material is replicated and then divided equally between the two daughter cells. This process is essential for the growth and development of organisms, as well as for the repair and replacement of damaged or worn out cells. Mitosis also plays an important role in the reproduction of organisms, as it is the process by which new cells are created.
