Cell Theory:
What are the three parts (tenets) of the cell theory?
1. The cell is the basic unit of life
2. All living things are made of cells
3. Cells come from pre-existing cells
What did Schleiden and Schwann study and how did they influence the cell theory?
Schleiden-1838 (found that all plants are made of cells)
Schwann-1839 (found that all animals are made of cells)
What did Rudolf Virchow introduce to finish the cell theory?
He found that all cells must come from pre-existing cells and cannot appear spontaneously
What was Anton Van Leeuwenhoek's contribution to the cell theory?
He made over 500 microscopes and was able to see living one-celled organisms in pond scum and tooth plaque
What was Hooke’s contribution to the cell theory?
He looked at cork under a simple microscope, found shapes that reminded him of the rooms monks lived in and
called them cells
