- In mulitcellular organisms, celldivision is responsible for growth, maintanance, and repair. In some one-celled organisms, cell division is a methid of asexual reproduction.
- Mitosis- cell divison where the chromosomes are duplicated and then separated into two cells. Identical genetic information is passed from one organism to the other.
