1 Cell Theory

2 To Put It in Perspective
1564 Shakespeare is Born

3 Zaccharias Janssen 1590 Dutch Invented the first microscope

4 To Put It in Perspective
1596 Galileo invents first thermometer 1620 Mayflower lands at Plymouth Rock

5 Robert Hooke 1665 English The first to study and publish observations made through a microscope. Coined the term “cells”

6 Anton van Leeuwenhoek 1674 Observed tiny living organisms in drops of pond water

7 To Put It in Perspective
1709 Piano invented 1789 George Washington President

8 Matthias Schleiden 1838 Concluded that all plants are made up of cells

9 Theodor Schwann 1839 Concluded that all animal are made up of cells

10 Rudolph Virchow 1855 All cells come from existing cells

11 To Put It in Perspective
1876 First telephone 1885 Usable electricity

12 Cell Theory All living things are composed of cells
Cells are the basic units of structure and function in living things New cells are produced from existing cells
