A great majority of cell divisions that occur in the body involve mitosis.


Mitosis ensures that all the cells will have same number of chromosomes. It is important for the formation of new cells and maintaining the ploidy of the cells as the resulting daughter cells have the same amount of genetic information in them.

The purpose of mitosis is cell regeneration and replacement, growth and asexual reproduction.
Mitosis is the basis of the development of a multicellular body from a single cell.
Cells of the skin and digestive tract are continuously sloughed off and replaced by new ones due to mitotic division.
Some body parts of animals and plants can be regenerated by mitotic cell division.
Vegetative propagation in plants and budding in some animals also occurs due to mitosis.

Mitosis populates an organism's body with cells through out an organism's life. In single celled eukaryotes like yeast, mitotic division is a form of reproductive process that helps in adding new individuals in the population.
