Cell Division:Mitosis & Meiosis – Video tutorial-Watch Online
Mitosis and Meiosis describes the process by which the body prepares cells to participate in either asexual or sexual reproduction to make an entire organism.
Examples of Mitosis and Meiosis
Mitosis is the reproduction of skin, heart, stomach, cheek, hair etc. cells. These cells are “Autosomal” cells. This is also a form of “Asexual” reproduction, where one organism or cell reproduces itself. Some organisms that reproduce asexually are hydra, bacteria, and single celled organisms.
Meiosis is the production of sperm and egg cells. These cells are “Gamete” or “Sex” cells. Each cell has to go through the division process twice in order for the cell to end up with half the number of chromosomes. The cells pass on genetic information to the offspring. This is a form of “Sexual” reproduction, where one organism or cells reproduces by crossing with another organism or cell. Types of organisms that reproduce sexually are; plants, animals, and insects.
