Detailed explanation-1: -Mitosis creates identical copies of cells. For example, it creates new skin cells to replace dead skin cells. Gametes are the cells needed for reproduction. Unlike other cells, they are not produced through mitosis.
Detailed explanation-2: -Answer and Explanation: If mitosis did not take place, the outer layers of our skin cells would wear out and disappear altogether very quickly. This is because the epidermis, or outer layer of skin, constantly regenerates itself through the process of mitosis, or cell division.
Detailed explanation-3: -The skin cells go through mitosis to replace dead ones. In order to create haploid gametes, meiosis takes place in the germ cells.
Detailed explanation-4: -In the skin, mitosis occurs in the epidermis, specifically in the stratum basale. The stratum basale produces cells that replace the dead cells lost from the epidermis.
