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.
