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.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.
"A" greek meaning "without."
"Sex" Greek meaning "to cross."
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 insect.
Mitosis: -- One cell becomes two cells-- The new "daughter" cell has exactly the same number of chromosomes and information as the "parent" cell. 1 cell divides and becomes 2 cells.
Meiosis: -- One cell becomes 4 cells--There are 4 new "daughter" cells. Each new gamete cell contains only one-half of the number of chromosomes of the parent cell. Each sex cell goes through the division process twice in order to have the correct number of cells, and the correct chromosomal information.
