Answer:
Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Mitosis is also the basis for healing wounds and fighting off invading pathogens that cause sickness. Certain organisms lose millions of cells per day as part of their normal function. Mitosis allows old cells to be replaced by new ones, ensuring an army of fully functioning cells.
