Mitosis and Meiosis and Sexual reproduction:
This tutorial on Mitosis and Meiosis has been provided by: Khan academy
Mitosis is a process of cell duplication, or reproduction, 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 mibranes. Meiosis is useful for sexual reproduction of organisms; The male and female sex cells, e.g. the spermazoa and egg, fuse to create a new, singular biological organism.
