Answer. Our skin cells divide rapidly in order to maintain a protective barrier against infection. The outer skin layer is called the epidermis and contains mostly dead cells that contain keratin.

Where are skin cells undergoing mitosis continuously?
The epidermis is composed of several layers: The stratum basale or stratum germinativum undergoes constant mitosis to replace the cells exfoliated from the skin’s surface.

Why are your skin cells continually undergoing mitosis?
The epidermis cells are constantly undergoing mitosis so that the outer dead cells containing keratin are rapidly replaced as they fall off, which occurs after so many days. Then the newer living cells start producing keratin, lose their cellular contents, and die, and the cycle goes on.

What happened to skin cells of mitosis did not take place?
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.

What cells in the body constantly undergo mitosis?
The cells that undergo mitosis most rapidly within the body are the cells that receive abrasion daily or are within a chemical environment. These cells include skin cells, cells within your cheeks, and stomach cells. Because these cells are within these harsh conditions, it is important that they undergo mitosis often.

Does skin cells go through mitosis?
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. A diagram of this event is given.

Why does a skin cell need to divide more frequently than a liver cell?
Skin cells need to be replaced more often than liver cells, so they have a higher rate of cell division. Since skin cells are exposed to wear and tear, they have to be replaced often. Meanwhile, liver cells and other internal cells have a longer lifespan.

What would happen to cells if mitosis did not take place?
Mitosis is the process by which cells divide. Without it, you could make no new cells. The cells in most of your body would wear out very quickly, greatly shortening your life.

What would happen if skin cells couldn’t divide?
In order for our bodies to grow and develop, they must produce new cells—and allow for the death of old cells. Cell division is also an essential component of injury repair. If our cells couldn’t divide and create new cells, our bodies could never produce new skin cells to heal road rash, or grow a fingernail back.

How does mitosis affect our skin?
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.
