What is the basic building

uint?

Animals

Bird

Plants

All living things have different

sizes, and shapes.

What is the basic building unit that

all living organisms have in

common ?

They are all made of cells

Who discovered the cells?

1- Leeuwenhoek made the best single lens microscopes in the world at that time.

Leeuwenhoek’s Microscope

Some of the cells that Leeuwenhoek Saw

2- Robert Hooke’s microscope

Robert Hooke saw little compartments;

he called them“Cells”

3- Robert Brown

was a botanist

and he studied

plants.

Robert Brown was the first person to

identify the cell nucleus.

5- Schwann.

Schwann discovered that animals

are also made up from cells.

6- Rudolf Virchow

Rudolf Virchow concluded that all cells

come from other cells.

Together, Schleiden, Schwann and Virchow

came up with the cell theory
