Question

why is mitosis important for tissue repair?
a. it removes toxins from the cell.
b. it increases genetic diversity in cells.
c. it produces new cells to replace damaged or dead cells.
d. it decreases the number of cells in a tissue.

Explanation:

Mitosis is a process of cell division. In tissue repair, its main role is to generate new cells. When tissues are damaged (cells are dead or damaged), mitosis occurs to produce more cells. Option a is about detoxification (not mitosis function). Option b (genetic diversity) is more related to meiosis. Option d is incorrect as mitosis increases cell number (for growth and repair). Option c is correct as it states mitosis produces new cells for replacement.

Answer:

C. It produces new cells to replace damaged or dead cells.
