From where do new cells originate?

New cells typically originate from the division of pre-existing cells through a process called cell division. Cell division can be classified into two main types: mitosis and meiosis. Von Mohl first proposed cell division. According to cell theory, all cells originate from pre-existing cells, and this process is essential for the growth, development, and repair of living organisms. While chemicals and amino acids play critical roles in cellular processes, they do not directly give rise to new cells.
