What is Mitosis?

Mitosis is when a cell divides into two cells and makes a new cell. The new cels can be used to make or replace damaged cells or just to make more cells as you get older.

Why is mitosis important?

Mitosis is important because if cells in our body are damaged, destroyed or killed. We also need mitosis because when we grow older and our bodies get larger, we need more cells. Without mitosis we would not live very long.
