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: -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-3: -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.
