Discovering the Cell

Robert Hooke Author of “Micrographia.” First coined the word “cell” to describe what he saw in a thin slice of cork.

Anton van Leeuwenhoek

Leeuwenhoek’s Microcscope

Cell discoveries in the 19th century Discovery of the nucleus: 1833 (Robert Brown) Description of cell division: 1879 (Walter Fleming)

The Electron Microscope Invented 1938 by Ernst Ruska. Allowed scientists to look into the cell in much greater detail.

Ruska’s Microscope

TEM: Cell Membrane

SEM: Cell Membrane
