AP BIOLOGY

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.

Detailed explanation-2: -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.

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. Meiosis occurs in germ cells while mitosis occurs in somatic cells.

Detailed explanation-4: -Mitosis is important to multicellular organisms because it provides new cells for growth and for replacement of worn-out cells, such as skin cells.
