• new cells can be generated from old cells.
• The establishment of the cell theory reveals the unity of cells and the unity of the structure of organisms, marking that biological research has entered the cellular level, which greatly promotes the research process of biology.
• The establishment of the cell theory clarifies that cells are the basic unit of the structure and function of living organisms, and are the basis for biological growth and development. 
• The establishment and development of the cell theory explained the unity of biology, and also clarified the basis of the morphogenesis of animals and plants.
