Which one of the following is not a reason for cell reproduction
a) repairing damaged cells
b) tumor suppression
c) growing new cells
d) reproducing organisms

B. Tumor Suppression

Explanation:

Tumors are characterized by an overgrowth of cells of the tissue which have developed in the tumor. The body has several tumor suppression mechanism that allow it to prevent cells from growing unnecessarily of their own accord. Normal cell reproduction will never occur for the purpose of tumor suppression because it would have the opposite effect (growth of tumor following uncontrolled cell growth or reproduction).

Cell reproduction is essentially in the formation of new cells and the repairing and replacing of damaged and dead cells, as well as a vital component that sustains reproducing organisms following the production of gametes.
