What is the relationship between cell division and growth?
dimulka [17.4K]

Answer:

The relationship between cell division and cell growth is that cell division needs to occur for the cells to divide and grow individually.

Explanation:

cell division refers to the process by which the mother cells divides into two daughter cells and cell growth refers to the process by which the size of the cell increases as it grows. They are two different but important and interlinked processes in the cell cycle. They depend on each other as failure in one will lead to failure in the other process too. The cell needs to grow proper in order to divide and create more cells.
