The Cell Theory
By: Verenice Rodriguez
The Parts Of The Cell Theory
There are three parts to the cell theory. The three parts include:
1. All organisms are composed of one or more cells.
2. The cell is the most basic unit of structure, function, and organization in all organisms.
3. All cells arise from pre-existing, living cells.
Robert Hooke
In 1665, Robert Hook was the first person to ever discover the living cells. Through his very thin slices of bottle cork, he noticed there were little compartments, like those of a monk. Therefore, he named them cells, due to them looking like little monk cells.
Anton van Leeuwenhooke
In 1674, Anton van Leeuwenhoek was the first to witness living cells under a microscope. He described the algae as animalcules, meaning "little animals." While looking at the cells, it is likely he also saw bacteria too.
Theodor Schwann
In 1838, Theodor Schwann took part in making the cell theory. He, Matthias Jakob Schieden, and Rudolf Virchow all had a part in the cell theory. Theodor and Matthias both agreed the cell was the basic unit of life.
Matthias Jakob Schieden
In 1838, Matthias also took part in the cell theory. He also recognized the importance of the nucleus. He was also the first German biologist to accept the theory of evolution.
Rudolf Virchow
In 1858, Rudolf was the first to recognize leukemia cells. He also thought that cell division only occurred in certain cells. He also took part in the discovery of the cell theory.
