Cell division : Meiosis and Mitosis
Mitosis is a process of cell duplication or reproduction during which one cell gives rise to two genetically identical daughter cells.
Meiosis is a division of germ cells 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.
|A type of cellular reproduction in which the number of chromosomes are reduced by half through the separation of homologous chromosomes, producing two haploid cells.
|A process of asexual reproduction in which the cell divides in two producing a replica, with an equal number of chromosomes in each resulting diploid cell.
|Cellular Reproduction & general growth and repair of the body
|Type of Reproduction
|Humans, animals, plants, fungi
|Yes, mixing of chromosomes can occur.
|No, crossing over cannot occur.
|Pairing of Homologous Chromosomes
|Number of Divisions
|Number of Daughter Cells produced
|4 haploid cells
|2 diploid cells
|Reduced by half
|Remains the same
|The steps of meiosis are Interphase, Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II and Telophase II.
|The steps of mitosis are Interphase, Prophase, Metaphase, Anaphase, Telophase and Cytokinesis
|Occurs in Interphase I
|Occurs in Interphase
|Occurs in Telophase I & Telophase II
|Occurs in Telophase
|The centromeres do not separate during anaphase I, but during anaphase II
|The centromeres split during Anaphase
|Sex cells only: Female egg cells or Male sperm cells
|Makes everything other than sex cells
|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.
