We need cells to live in the same way that we need bricks to make buildings.
Every part of our body is made of cells, and without them we simply wouldn't exist.
Why do we need cells Cells are the building blocks of our body - each of us is made up of trillions of cells, and each of those has a particular job to do.
Cells have a common structure, and are made up of tiny particles that keep the cell structure functioning.

Fun facts about cells Cells are fascinating little things, and it can sometimes be hard to imagine that we are made up of trillions of tiny individual ones.

- An ostrich egg's yolk is the largest single cell on the planet
- Cells commit suicide when they become infected or damaged
