In 1838, the cell theory was established by two German biologists, Matthias Schleiden and Theodor Schwann. This theory revolutionized the field of biology by providing a unifying concept for all living organisms. Let’s delve into the story of how this theory was discovered.
The Beginnings of Cell Theory
Before Schleiden and Schwann established the cell theory, scientists were aware that all living things were composed of cells. However, they did not understand the significance of this fact. It was not until the early 19th century that researchers began to realize that cells were not just structural units but also functional entities.
Matthias Schleiden
Matthias Schleiden was born in Hamburg in 1804. He studied law and then natural sciences at the University of Jena. In 1835, he became a professor of botany at the University of Jena, where he began his research on plant cells.
Schleiden observed plant tissues under a microscope and discovered that every part of a plant was composed of cells or their derivatives. He also concluded that new cells could only arise from pre-existing ones.
Theodor Schwann
Theodor Schwann was born in Neuss in 1810. He studied medicine at the University of Bonn and then went on to become a professor at various universities in Germany and Belgium. In 1836, he turned his attention to animal tissues.
Schwann examined different types of animal tissues and determined that they were all made up of cells or their products. He also realized that the basic structure and function of animal cells were similar to those of plant cells.
The Discovery
In 1838, Schleiden published his findings on plant cells in a book called “Contributions to Phytogenesis.” In this book, he proposed that plant tissues were made up of cells and that new cells were formed from pre-existing ones.
The following year, Schwann published his observations on animal tissues in a book called “Microscopic Investigations on the Accordance in the Structure and Growth of Plants and Animals.” In this book, he stated that animal tissues were also composed of cells and that the basic structure and function of animal cells were similar to those of plant cells.
Together, Schleiden and Schwann realized that all living things were composed of cells or their derivatives. They also recognized that new cells could only arise from pre-existing ones. This led them to propose the cell theory – the idea that all living things are composed of one or more cells, and that the cell is the basic unit of life.
Conclusion
In conclusion, Matthias Schleiden and Theodor Schwann discovered the cell theory in 1838. Their work revolutionized biology by providing a unifying concept for all living organisms. Today, we continue to build on their discoveries as we explore the complexity of life at the cellular level.
