• It was developed by many scientists working together happily.

• It was developed by many different scientists over a long period of time.

​Please write the following in your notes:

​1665 – Robert Hooke: First to observe cells through a rudimentary microscope. He observed cork cells, and coined the term “cells."

​*Hooke May have looked like this, but we aren't sure!

​Keep going!

​1674 – Anton von Leewenhoek Observed the first living cells in teeth scrapings pond water. He called them “wee beasties" and animalcules.

​Next Up - Write this down!

​1838 – Mattias Schleiden Botanist (studied plants) who concluded that all plants and plant parts are made of cells. 

​And his partner...

​1839 – Theodor Schwann Zoologist (studied animals) who conclude that all animals are made of cells.

​The final piece of cell theory...

​1855 – Rudolph Virchow After looking at many different types of cells, he concluded that all cells come from pre-existing cells. 

​But Wait! There's More!

​** If you run out of room, please use the back of your paper!

​1970 – Lynn Margulis Developed Endosymbiotic Theory. This is the idea that complex eukaryotes evolved when larger prokaryotes engulfed smaller prokaryotes. The two then formed a mutually beneficial relationship that led to a new organism.

​

​Endosymbiotic Theory Continued:
