Detailed explanation-1: -Skin cells, red blood cells or gut lining cells cannot undergo mitosis.

Detailed explanation-2: -While these connective tissue cells and epithelial cells can undergo mitosis and regenerate themselves upon damage or to replace the older ones, the main brain cells or the neurons cannot undergo mitosis. Their number remains the same from birth.

Detailed explanation-3: -The cells which do not divide by mitosis are differentiated cells and sex cells. These differentiated cells embody neurons, muscle cells, skin cells, and most blood cells, B-cells, T-cells, and red blood cells.

Detailed explanation-4: -There is absence of centrioles in the nerve cells and because of this they are unable to perform mitosis and meiosis and hence these cells do not divide. But nerve cells get longer without dividing and they do not divide during their lifetime.

Detailed explanation-5: -What types of cells do not undergo mitosis? Sperm cells and egg cells don’t go through mitosis.
