CELL DAMAGE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What type of cells may never undergo mitosis and make new cells?
A
blood cells
B
skin cells
C
nerve cells
D
stomach cells
Explanation: 

Detailed explanation-1: -Nerve cell does not divide because they do not have centrioles, so they cannot undergo mitosis and divide to form new cells.

Detailed explanation-2: -Skin cells, red blood cells or gut lining cells cannot undergo mitosis. Stem cells do divide by mitosis and this makes them very important for replacing lost or damaged specialized cells.

Detailed explanation-3: -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.

Detailed explanation-4: -The body cells that do not undergo mitosis are germ cells. The germ cells are the reproductive cells (egg in the female and sperm in the male) and undergo meiosis. Meiosis is the cell division in which the parent reproductive cell divides into daughter cells with half the number of the parent’s chromosomes.

Detailed explanation-5: -Nerve cells do not undergo cell division due to absence of centrioles which help in assembling of microtubules during the process of cell division. Nerve cells in fact develop from glial cells by the process of neurogenesis.
