2 DO NOW ANSWERS The microscope has made it possible to investigate a world that we cannot see with our naked eye The cell is the basic unit of life BUT WHAT DOES THAT MEAN? It means that it builds ALL living things and it is capable of performing ALL life processes

3 Francisco Redi Living things come from other living things
Maggots come from flies which lay eggs on decaying meat

4 How did we discover the cell?
The microscope

5 Who discovered the first microscope
1590 Hans and Zacharias Janssen Ground up glass and used it to magnify

6 Robert Hooke discovered cell

7 1605 Robert Hooke Looked at cork plant
