Detailed explanation-1: -Schleiden believed cells came from a process called free cell formation, or spontaneous generation. This idea stated that cells could arise from non-living matter. Schwann however, believed cells came from preexisting cells.
Detailed explanation-2: -In 1838 Schleiden defined the cell as the basic unit of plant structure, and a year later Schwann defined the cell as the basic unit of animal structure. Schleiden and Schwann articulated their observations as a unified theory-the cell theory-in 1839.
Detailed explanation-3: -Eventually, Schneidan and Schwann joined forces and started to develop the cell theory. But they disagreed on the third point: that all cells come from preexisting cells. It took a third scientist, Rudolf Virchow, to prove that cells did indeed come from other cells.
