There are two main types of cell division:

* Mitosis: This is the process by which a single cell divides into two identical daughter cells. It's used for growth, repair, and asexual reproduction.

* Meiosis: This is the process by which a single cell divides into four non-identical daughter cells. It's used for sexual reproduction, creating gametes (sperm and egg cells) with half the number of chromosomes as the parent cell.
