Rudolf Virchow's contribution to the cell theory was that he concluded that all cells come from preexisting cells. This is known as the principle of biogenesis. Virchow rejected the idea of spontaneous generation, which was a popular hypothesis at the time, and instead proposed that cells can only arise from preexisting cells through cell division. This notion is a fundamental aspect of the cell theory, which states that all living organisms are composed of cells, cells are the basic units of structure and function, and cells come from preexisting cells.
