Question

Through the process of differentiation bone cells are formed and they cannot return to stem cells. Why then can a broken bone heal?

A) The process of mitosis allows the old bone cells to divide and produce new bone cells.
B) The process of meiosis allows for the reproduction of bone cells
C) The process of differentiation occurs again and produces new bone cells.
D) The process of reproduction happens and produces new bone cells.

Answer 1

A) The process of mitosis allows the old bone cells to divide and produce new bone cells.

Answer 2

Option (A).

Step-by-step explanation:

Mitosis can be defined as a type of cell division that produces two identical daughter cells from a single parent cell. Mitosis is responsible for growth and repairing of old or damaged cells.

When bone breaks, mitosis occurs in pre-existing bone cells, which leads to formation of new bone cells to heal broken bone.

Thus, the correct answer is option (A).
