The Cell Theory

1. All living things are composed of cells.

2. Cells are the basic units of structure and function in living things.

3. All cells are produced from other cells.

1590

This father and son team are given credit for inventing the first compound microscope.

Hans and Zacharias Janssen• Zhacharias most likely had help from his

father Hans.• Could magnify 3 to 9 times (maybe up to 10x)• Would be more than 50 years before the

microscope was used by scientists.

especially cork.

Robert Hooke’s Drawing of Cork

• Thought the chambers looked like little rooms in the monastery.

• Called them “cells”

1674

Dutch lens maker who was the first to identify bacteria by looking at scrapings from his

teeth

Anton Van Leeuwenhoek

Leeuwenhoek was not a good artist so he described in great detail what he saw under the microscope.

1839

This German scientist extended the work of his friend Matthias Schleiden and discovered that ALL cells (plants and animals)

were made of cells.

Rudolf Virchow

Virchow applied his ideas to disease. He thought that all disease was caused by cells that did not function properly.
