The process by which new cells are formed for growth, repair and replacement in the body.

Explanation:
New cells for growth, repair, and replacement come from cell division. In the body, most growth and tissue healing occur through mitosis, where a cell duplicates its DNA and then splits to form two genetically identical daughter cells. This process also handles the ongoing turnover of cells that wear out, keeping tissues functioning properly. Digestion is the breakdown of food in the stomach and intestines. Metabolism covers all the chemical reactions in the body, including energy production and synthesis of molecules. Respiration refers to cellular respiration, the process that releases energy from nutrients using oxygen. While those processes are essential for life, they do not describe the formation of new cells for growth and repair the way cell division does.
