Answer: Mitosis
Explanation:
Since meiosis helps only in the production of gametes, mitosis helps the somatic cells in the already fertilized egg (zygote) to do the following:
- multiply their number, thus aiding growth
- form new cells like red blood cells to transport oxygen, white blood cells to fight infection, liver cells etc
Thus, for growth mitosis is the mechanism used to generate more cells
This is called the metabolism. Hope this helps.
