This process is what is behind the growth of children into adults, the healing of cuts and bruises, and even the regrowth of skin, limbs, and appendages in animals like geckos and lizards. In mitosis, a cell makes an exact clone of itself. Not only is mitosis responsible for asexual reproduction in single-celled organisms, but it is also what enables cellular growth and repair in multicellular organisms, such as humans. Though both types of cell division are found in many animals, plants, and fungi, mitosis is more common than meiosis and has a wider variety of functions. What is the role and purpose of mitosis and meiosis?

The centromeres do not separate during anaphase I, but during anaphase II. All cells except sex cells (aka germ cells or gametes) are created via mitosis. Sex cells only: female egg cells or male sperm cells. Occurs in Telophase I and in Telophase II. Genetic diversity through sexual reproduction.Ĭellular reproduction and general growth and repair of the body. Meiosis does not occur in archaea or bacteria because they reproduce asexually. Meiosis occurs in all organisms that reproduce sexually e.g., all eukaryotes - humans, animals, plants, fungi. Prophase, Metaphase, Anaphase, Telophase. (Meiosis 1) Prophase I, Metaphase I, Anaphase I, Telophase I (Meiosis 2) Prophase II, Metaphase II, Anaphase II and Telophase II.

Comparison chart Meiosis versus Mitosis comparison chartĪ type of cellular reproduction in which the number of chromosomes are reduced by half through the separation of homologous chromosomes, producing two haploid cells.Ī process of asexual reproduction in which the cell divides into two daughter cells, with an equal number of chromosomes in each resulting diploid cell.
