Detailed explanation-4: -Cells can grow by increasing the overall rate of cellular biosynthesis such that production of biomolecules exceeds the overall rate of cellular degradation of biomolecules via the proteasome, lysosome or autophagy.

Detailed explanation-5: -Mitosis happens in all eukaryotic cells (plants, animals, and fungi). It is the process of cell renewal and growth in a plant, animal or fungus. It is continuously occurring throughout our bodies; it is even happening while you are reading this.
