Detailed explanation-1: -Mitosis is necessary for cell growth, repair, and regeneration. Dead cells are replaced by mitosis since the number of chromosomes is not changed in a cell after division in mitosis.

Detailed explanation-2: -Mitosis is important to multicellular organisms because it provides new cells for growth and for replacement of worn-out cells, such as skin cells. Many single-celled organisms rely on mitosis as their primary means of asexual reproduction.

Detailed explanation-3: -When cells become damaged or die the body makes new cells to replace them. This process is called cell division.

Detailed explanation-4: -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-5: -During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes. When mitosis is not regulated correctly, health problems such as cancer can result.
