Cells use a special kind of timer to know when to split. Imagine you're playing a game, and every time you complete a level, you get a point. When you reach 10 points, the game lets you start again with a new character, just like how cells divide when they have enough energy and space.
Examples
- A seed grows into a tree by dividing its cells many times.
- When your skin gets a cut, new cells divide to heal it.
- Bacteria multiply by splitting in two every few minutes.
