NEET BIOLOGY

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: -Despite the fact that neurons, like many other specialized cells contain a nucleus, they do not possess centrioles, which are essential for cell division. As neurons develop, they do not produce these key organelles, making replication impossible.

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