3. Before the invention of the microscope, people didn’t know anything existed smaller than what the eye could see.

4. The contributions of many scientists helped develop the Cell Theory:
All organisms are made up of cells
Cells are the basic unit of structure and function
Cells come from pre-existing cells

5. Robert Hooke (1665) Observed cork and called them cells; they reminded him of the small rooms of monks.

6. Anton Von Leeuwenhoek (1665) Observed pond water and saw tiny moving creatures (protists)

7. Matthias Schleiden (1800) Observed plants and determined that all plants are composed of cells

8. Theodor Schwann (friend of Schleiden) Observed animal cells and determined all animals are composed of cells

9. Schleiden and Schwann share their findings…

10. Rudolf Virchow (1850s) Observe cells dividing
Rudolf Virchow (1850s) Observe cells dividing. He concludes that all cells come from pre-existing cells.
(Paramecium dividing: play several segments)

11. As the technology improved, our understanding of how cells functioned also improved.
