The division and reproduction of the cells is called Mitosis and Meiosis. Mitosis is a process of cell division that results in two genetically identical daughter cells developing from a single parent cell. On the other hand, Meiosis is the 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 membranes. Meiosis is found in sexual reproduction of organisms. The male and female sex cells (ex. egg and sperm) are the end result of meiosis, they combine to create new, genetically different offspring. Though both types of cell divisions are found in many animals, plants, and fungi, mitosis is more common than meiosis and has a wider variety of functions. Not only is mitosis responsible for asexual reproduction in single-celled organisms, but it is also what enables cellular growth and repairs in multicellular organisms, such as humans. In mitosis, a cell makes an exact clone of itself. This 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.
Meiosis is a more specific type of cell division (of germ cells) that results in gametes, either eggs or sperm, that contain half of the chromosomes found in a parent cell. Unlike…
