Who is Theodor Schwann and what did he discover?
In 1838 Matthias Schleiden had stated that plant tissues were composed of cells. Schwann demonstrated the same fact for animal tissues, and in 1839 concluded that all tissues are made up of cells: this laid the foundations for the cell theory. Schwann also worked on fermentation and discovered the enzyme pepsin.
Schleiden preferred to study plant structure under the microscope. While a professor of botany at the University of Jena, he wrote Contributions to our Knowledge of Phytogenesis (1838), in which he stated that all parts of the plant organism are composed of cells.
- Scientists Who Contributed To The Cell Theory
- Robert Hooke. 1665 -English scientist that cut a thin slice of cork and looked at it under his microscope.
- Anton Van Leewenhoek.
- Matthias Schleiden.
- Theodor Schwann.
- Rudolph Virchow.
- The Cell Theory.
- Francesco Redi.
- Louis Pasteur.
- The Francesco Redi Experiment. Francesco Redi was able to disprove the theory that maggots could be spontaneously generated from meat using a controlled experiment. Spontaneous generation, the theory that life forms can be generated from inanimate objects, had been around since at least the time of Aristotle.
- The invention of the microscope made the discovery of cells possible. 2. Robert ooke used the name cells to refer to the tiny empty chambers he saw when he observed magnified cork.
