1. Microscopes, Spontaneous Generation & Cell Theory

2. Spontaneous Generation
Living things can come from non-living matter
toads from mud, mice from grain + rags

3. Redi = first to disprove spontaneous generation with science
Experimental Set-up:
Control Set-up

4. Pasteur
Experimental Set-up:
Control Set-up:
Conclusion:

5. Robert Hooke First to see cells The cork cells - dead only cell walls.
Named after monk’s cells
Little empty rooms

6. Anton van Leeuwenhoek
Saw first LIVE cells in pond water.

7. Schleiden, Schwann & Virchow = Cell Theory
1. All living things have cells
Schleiden = all plants
Schwann = all animals
2. Cells are the basic unit of life
3. All cells come from other cells.

8. Microscope Types 1. Compound Light Microscopes a. More than one lens
b. use light to create image
2. Electron microscopes
a. use electrons to create image
b. can see things smaller than the
wavelength of light
