Mitosis Vs. Meiosis by Justin

Mitosis and meiosis two processes that sound similar yet have many different functions. Mitosis was discovered by Walther Flemming in 1882. Meiosis was discovered six years before Mitosis on 1876 by Oscar Hertwig.

Mitosis is an asexual reproduction and occurs in all organisms. The process happens about 24/7, especially when the body is damaged or bruised. Mitosis is used for growth and to repair the body. There are six steps in Mitosis; Interphase, Prophase, Metaphase, anaphase, telophase, and cytokynsis each of these stages are similar to Meiosis except cytokynsis. In Mitosis chromosomes remain the same and the cell divides only once. When the division is over the result is two genetically identical diploid cells.

As Meiosis the purpose is very different from Mitosis, Meiosis function is sexual reproduction and occurs only in eukaryote cells such as humans, plants animals, and fungi. The steps in Meiosis are Interphase, Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II and Telophase II. Meiosis has two divisions and does not create two genetically identical diploid cells; it makes four different Haploid cells. Chromosomes are reduced by half and Meiosis produces sex cells such as: Male sperm cells and Female egg cells.
