Where do meiosis and mitosis occur?

Posted November 30, 2023


Answer

Meiosis takes place in cells which are involved in sexual reproduction. In animals, female gametes are known as ova or egg cells, and male gametes are called sperm cells. These cells are found within the reproductive organs (testes and ovaries). Gametes are haploid cells meaning they only contain one set of chromosomes. They have half the genetic material necessary for forming a new organism. In contrast, mitosis takes place in non-reproductive cells also known as somatic cells. Somatic cells constitute various parts of the body including connective tissue, bones, internal organs, skin, and blood. Some examples of these cells include blood cells, skin cells, nerve cells, and muscle cells. It is important to note that mitosis takes place in all eukaryotes like humans, fungi, and plants, and is simply the process of cell division. On a side note, prokaryotes do not undergo mitosis or meiosis, and instead undergo binary fission to reproduce.
