  1. Microscopes and the Develop of the Cell Theory

  2. 1665 Robert Hooke

  3. Used Compound Light Microscope Find the lenses…Look at the light source!

  4. Aaaahhh! What is this?

  5. Aaaahhh! What is this?

  6. 1665 HOOKE –namedcells after looking at cork (cell walls) and seeing the resemblance to monk cells

  7. 1673 Anton von Leeuwenhoek

  8. Createdsimplemicroscopes that could magnify 200-400 x’s!

  9. Credited for observing living organisms, or “animalcules”

  10. His animalcules…Little BEASTIES!

  11. 1838 Matthias SCHLIEDEN 1839 Theodor SCHWANNplants are made of cellsanimalsare made of cells

  12. 1855 Rudolf VIRCHOW: cells come from other cells

  13. Cell Theory • All organisms are made of cells • Cells are the basic unit of structure & function • Cells come only from preexisting cells

  14. LIGHT MICROSCOPE • Uses light and lenses to directly observe specimens • Compound: 2 lenses, multiply lens powers • Simple: 1 lens
