Cell Theory and the Cell

Cell Theory and the Cell. Cell Theory. Term “cell” was coined in 1665 by Robert Hooke He looked at a slice of dried cork All living things are comprised of cells. Cells are the smallest “living” unit in an organisms. Cells come from previously existing cells. Cell Diversity.

The Cell Theory

The Cell Theory. 1. Discovery of the Cell. 1665- English Scientist, Robert Hooke , discovered cells while looking at a thin slice of cork. Anton van Leuwenhoek - 1673- Used a handmade microscope to observe pond scum & discovered single celled organisms . He called them “animalcules.”.

Cells and Cell Theory

Cells and Cell Theory. Early Microscopes. Robert Hooke built a microscope in 1665 He looked at cork from trees and saw tiny boxes. He called them cells . Hooke spent most of his time looking at plants and fungi. He thought that only plants had cells because they were easier to see.
