Here's why:
* Cell Growth: A cell grows by increasing its size and volume through processes like protein synthesis and organelle production.
* Mitosis: Mitosis is the division of the nucleus and the separation of chromosomes, followed by cytokinesis (division of the cytoplasm) to form two identical daughter cells.
Think of it this way:
* Growing: Like a balloon being inflated with air.
* Mitosis: Like cutting the inflated balloon in half to create two smaller balloons.
While mitosis is necessary for the growth of multicellular organisms by increasing the number of cells, it is not the process of individual cell growth itself.
