In biology, the cell theory is a scientific theory that describes the properties of cells, which are the basic unit of structure in all organisms and the basic unit of reproduction. The cell theory is a widely accepted explanation of the relationship between cells and living things.
The three main ideas to the cell theory are:
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
The initial development of the theory was made possible by the observations of Robert Hooke,Anton Van Leeuwenhoek,Matthais Schleiden, Therdor Schwann,Rudolf Virchow, which led to the development of the cell theory.
Anton Van Leeuwenhoek
Born on October 24, 1632 Anton Van Leeuwenhoek was considered to be the first microbiologist. He is best known for his work on the improvement of the microscope and for his contributions in the establishment of microbiology. Using his handcrafted microscopes, he was the first to observe and describe single-celled organisms, which he referred to as animalcules. They are now referred to as microorganisms. He was also the first to record microscopic observations of muscle fibers, bacteria, spermatozoa, and blood flow in capillaries (small blood vessels).
Born on October 13, 1821, Rudolf Virchow was a German doctor, anthropologist, pathologist, prehistorian, biologist, writer, editor, and politician, known for his advancement of public health. He is credited with important discoveries. His most widely known scientific contribution is his cell theory, which built on the work of Theodor Schwann. He is cited as the first to recognize leukemia cells.
