Detailed explanation-1: -Some cells, like skin cells, are constantly dividing. We need to continuously make new skin cells to replace the skin cells we lose.

Detailed explanation-2: -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-3: -But some cells, such as skin cells or blood cells are dividing all the time. When cells become damaged or die the body makes new cells to replace them. This process is called cell division.

Detailed explanation-4: -Constantly dividing cell types include skin cells, cells in the gastrointestinal tract and blood cells in the bone marrow. Many more types of cells in the body are constantly or regularily dividing, albeit at a very slow rate.

Detailed explanation-5: -Possible Answer: Skin cells divide more often. The cell cycle is shorter, which means that they go through mitosis more frequently. This is so because skin cells need to be replaced more frequently than kidney cells do.
