Hmmm.... What should be the name for the basic structure of all living things?
Oh, I got it! Cells!!
Robert Brown
Something in a cell has to control its processes and carries its DNA.
Yes, that's it! The nucleus!
Theodor Schwann
All animals are made out of cells!
Hmm... All my studies have led to a certain fact!
Robert Hooke discovered the term, cells, in 1665. This led to further discoveries about cell theory.
Matthias Schleiden
So, Schwann says that all animals contain cells? Maybe all plants contain cells too!
Robert Brown was the discoverer of the nucleus. He discovered this in 1831 while investigating the fertilization mechanisms in plants.
Rudolf Virchow
How do cells form? They can't just randomly appear.
Schwann came up with part of the cell theory. This part was, "All animals are made up of cells. He cofounded cell theory along with Matthias Schleiden.
Conclusion
We did it! We figured out Cell Theory!
Schleiden contributed to cell theory by coming up with the term "All plants are made of cells." He and Theodor Schwann worked together to find out that "All living things are made out of cells." This is one of the parts of the cell theory.
Virchow came up with the idea that cells multiply to make copies of themselves, increasing the number of cells. This helped contribute to cell theory and helped scientists understand cells more thoroughly.
Oh! I got it! All cells come from other cells, meaning they multiply to reproduce.
Cell Theory was discovered by many scientists, including Robert Hooke, Robert Brown, Theodor Schwann, Matthias Schleiden, Rudolf Virchow, and others. The three principles of cell theory are, all living things are composed of cells, cells are the basic units of living things, and cells come from other cells. These scientists helped discover these principles of Cell Theory causing a better understanding of cells.
