A cell is like a tiny factory where all the jobs to keep us healthy and alive happen.
It’s the most basic, smallest unit of life that can operate on its own or together with others.
Cells were first discovered in 1665 by a man named Robert Hooke, using a special instrument called a microscope.
He named them ‘cells’ because they reminded him of the tiny rooms monks lived in, also called cells.
Now, everyone uses this name to describe these important tiny parts of all living things.
There are many different types of cells, just like there are many different types of jobs in a factory.
Some cells are responsible for giving your body energy, like tiny power plants.
Others, like white blood cells, act like soldiers to protect your body from germs and diseases.
Each cell has special areas called ‘organelles’ that help it do its job effectively, just like every factory has different sections where specific tasks are done.
