Detailed explanation-1: -Mitosis is how somatic-or non-reproductive cells-divide. Somatic cells make up most of your body’s tissues and organs, including skin, muscles, lungs, gut, and hair cells.

Detailed explanation-2: -Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell.

Detailed explanation-3: -Every day, our skin cells and other somatic (body) cells undergo division to replenish the dying cells. When this happens, the new cell will have the same amount of chromosomes and organelles. This process is called mitosis.

Detailed explanation-4: -Basal cells constantly undergo mitosis in the stratum basale, dividing to produce new skin cells that will replace the dead ones. These skin cells, called keratinocytes, migrate upward into the upper epidermal layers. They mature as they move, filling with the protein keratin.
