Explanation:
Cell division is the process that occurs in all living organisms by which a cell divides into two or more daughter cells. The purpose of vegetative cell division (mitosis) in eukaryotes is maintenance of the cell's genome, growth by cell multiplying and tissue renewal by producing new cell. Reproductive cell division-meiosis is responsible for the formation of gametes for the further reproduction. In prokaryotes it is used as a form of reproduction ( binary fission).
