Mitosis:
* Skin: The outer layer of skin (epidermis) is constantly being replaced as cells are shed. Mitosis is responsible for producing new skin cells to maintain this layer.
* Bone Marrow: Red blood cells, white blood cells, and platelets are produced in the bone marrow. Mitosis ensures a constant supply of these essential blood cells.
* Intestinal Lining: The lining of the digestive tract is constantly being replaced as cells are worn down. Mitosis is responsible for generating new cells for this lining.
Meiosis:
* Ovaries (females): Meiosis occurs in the ovaries to produce egg cells (ova). Each egg cell contains half the number of chromosomes as a normal body cell.
* Testes (males): Meiosis occurs in the testes to produce sperm cells. Each sperm cell contains half the number of chromosomes as a normal body cell.
Key Difference:
* Mitosis produces genetically identical daughter cells, used for growth, repair, and replacement.
* Meiosis produces genetically diverse gametes (sperm and egg cells) with half the number of chromosomes, essential for sexual reproduction.
