| cell cycle | The normal sequence of growth, maintenance, and division in a cell. |
| interphase | The period in the cell cycle in which a cell grows, maintains itself, and prepares for division. |
| mitosis | The phase in the cell cycle during which the nucleus divides. |
| cytokinesis | The division of a parent cell's cytoplasm following mitosis. |
| asexual reproduction | The process by which a single organism produces offspring that have the same genetic material. |
| binary fission | A form of asexual reproduction by which some single-celled organisms reproduce. The genetic material is copied, and one cell divides into two independent cellst that are each a copy of the original cell. |
| regeneration | In some organisms, the process by which certain cells produce new tissue growth at the site of a wound or lost limb; also a form of asexual reproduction. |
