3. Introduction to Cells

4. Discovery of the cell
1665-Robert HOOKE saw the cell walls of cork and called them “CELLS”

5. 1673 Anton van LEEUWENHOEK saw the first living cells in a drop of water – “little animals”

6. 3 Discoveries that led to the Cell Theory
1838 Matthias SCHLEIDEN concluded all plants were composed of cells
1839 Theodor SCHWANN concluded all animals were composed of cells
1855 Rudolf VIRCHOW observed cell division.

7. The Cell Theory (3 parts)
All living things are composed of cells
Cells are the basic units of structure and function in an organism
Cells come only from the reproduction of existing cells

8. Cell Diversity Not all cells are alike
Sizes and shapes vary for structure and function
