What is the significance of the process of mitosis in cell repair?
Options
- AMitosis results in the formation of syncytium.
- BMitosis is essential for the cell to divide to restore the nucleo-cytoplasmic ratio.
- CMitosis contributes to the repair of damaged cells.
- DMitosis is only important in the growth of multicellular organisms.
Correct answer
C. Mitosis contributes to the repair of damaged cells.
Step-by-step solution
Mitosis usually results in the production of diploid daughter cells with identical genetic complement. Cell growth results in disturbing the ratio between the nucleus and the cytoplasm. It therefore becomes essential for the cell to divide to restore the nucleo-cytoplasmic ratio. A very significant contribution of mitosis is cell repair. The cells of the upper layer of the epidermis, cells of the lining of the gut, and blood cells are being constantly replaced. Mitotic divisions in the meristematic tissues – the ap
