All living matter is made of cells.
The cell is the basic structural unit of all life.
More than 300 years ago, an English scientist called Robert Hooke (1635-1703) looked at thin slices of cork
under the microscope.
This was the first time cells had been seen under the microscope.
He described the cork as a mass of tiny cavities which reminded him of the honeycomb of a bee.
So he called these structures cells.
In 1831, a British scientist observed a cell structure he called a nucleus.
In 1839, two German scientists developed what we now call the cell theory.
