History of the Cell Theory

The Cell Theory

1. All organisms are made up of one or more cells.

2. The cell is the most basic structure, function, and organization in all organisms.

3. All cells come from living cells.

Robert Hooke

He discovered cells from a piece of cork. He only saw the walls since the cork was dead, so they looked like cells in a monastery. Robert Hooke was the one who started calling cells cells.

Anton van Leeuwenhoek

He is a Dutch scientist who was the first to look at living cells through a microscope. He looked at the cells in pond water. He also was the first to discover protozoa and bacteria.

Robert Brown

He is an English botanist who discovered the nucleus in plant cells.

Matthias Jakob Schleiden

He was a German botanist who said that all plant tissue was made up of cells and that cells were the basic building blocks of all plants. He said the first generalized statement about cells.

Theodor Schwann

He was the German botanist who discovered two of the rules of the cell theory, cells are organisms and all organisms consist of one or more cells, and the cell is the basic unit of structure for all organisms.

Albrecht von Kolliker

He discovers that sperm and eggs are also cells.

Carl Heinrich Braun

Braun redoes the cell theory saying cells are the basic building unit of life.

Rudolf Virchow

Virchow created the last part of the cell theory saying cells only develop from existing cells. He also said diseased cells come from healthy cells. He was a German physiologist/ physician/ pathologist.
