Cell division and reproduction can occur in two ways - mitosis and meiosis.Mitosis is a process of cell division during which one cell gives rise to two genetically identical daughter cells.Meiosis, on the other hand, is a division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or sex cells, each possessing half the number of chromosomes of the original cell.Mitosis is used by single celled organisms to reproduce; it is also used for the organic growth of tissues, fibers, and membranes. Meiosis is useful for sexual reproduction of organisms. The male and female sex cells, e.g. the spermatozoa and egg, fuse to create a new, singular biological organism.

Meiosis and Mitosis are the two types of Cell division.Meiosis involves crossing over btwn homologous chromosomes and results in offsprings which r phenotypically and genetically different among them and from the parent.It takes place in reproductive/germinal cellsof sexually reproducing organisms.Four daughter cells are formed.While,Mitosis is a simple process which doesn't involve crossing over.Two daughter cells r formed, which r identical to each other and their parent.This occurs in somatic/body cells
