Presentation transcript:

Discovery of the Cell

Once upon a time, in the early 1600’s… Anton van Leeuwenhoek Built the first microscope and saw tiny organisms in pond water

Then, in 1665, Robert Hooke built a stronger microscope with a better lens and a light source Observed cork under the microscope Saw small “chambers” – called them CELLS

It wasn’t long before Robert Brown: - Discovered the Nucleus in 1831

Theodor Schwann (“Schwannimal”) And… Matthias Schleiden: Concluded that all plants are made of cells in 1838 Theodor Schwann (“Schwannimal”) Concluded that all animals are made of cells in 1839

Finally, in 1855, Rudolf Virchow: - Developed the Cell Theory

The cell theory states: 1. All living things are made of cells. 2. Cells make up the structure and perform all the functions of living things. 3. New cells come from pre-existing cells.
