Here's why:

* Mitosis is a process where a single cell divides into two identical daughter cells. This is how multicellular organisms grow and repair tissues. The new cells are genetically identical to the parent cell.

* Meiosis, on the other hand, is a type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell. This is important for sexual reproduction.
