Which type of cells are constantly being replaced by mitotic divisions?

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
