History of the Cell Theory

By Kendra Allard

The Cell Theory

The cell theory states three simple rules:

-every living thing has one or more cells.

-cells carry out the functions needed to support

-cells come only from other living cells

Robert Hooke:

Robert Hooke was the founder of cells. He made the discovery by looking at cork under a microscope in abut the 1660's. The cork cells were not living when he looked at it, so they looked empty, reminding him of vacant rooms- or cells.

Anton van Leeuwenhoek

Anton van Leeuwenhoek was the first to describe living cells in about the 1670's. When he looked at a drop of pond water under a microscope and to his surprise, it was full of living organisms at almost 300x.

Theodor Schwann

Theodor Schwann was a German botanist. In 1839, he came to a conclusion that animal tissue was made up of cells. He also wrote the Cell Theory, which was stated above.

Matthias Schealden

Matthias Schleiden, a German botanist, concluded that all plant tissues are composed of cells and that an embryonic plant arose from a single cell in 1838.
