Discovery of the Cell
Robert Hooke (1665)
•  Looked at nonliving cork through
early microscope.
•  Observed tiny empty chambers.
•  Called the chambers “cells”.
Anton van Leeuwenhoek
•  Looked at living organisms in the human mouth.
•  Today they are called “bacteria”.
p. 190
Discovery of the Cell
The Cell Theory
•  The cell discoveries made by
scientists were summarized in
the “cell theory”.
Cork Cells •  The cell theory states:
- All living things are made up of cells.
- Cells are the basic units in living things.
- New cells are produced from existing cells.
p. 191
Exploring the Cell
How do we observe cells?
•  Microscopes.
How do microscopes work?
•  They use lenses to magnify the image of an object by
focusing light or electrons.
