| Term | Definition |
|---|---|
| Cell division | process by which a cell divides into two new daughter cells |
| Chromatid | one of two identical "sister" part of a duplicated chromosome |
| Centromere | area where the chromatids of a chromosomes are attached |
| Interphase | period of the cell cycle between cell division |
| Cell cycle | series of events that cells go through as they grow and divide |
| Mitosis | part of eukaryotic cell division during which the cell nucleus divides |
| Prophase | first longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus. |
| Centriole | one of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope |
| Spindle | fan like microtubule structure that helps separate the chromosomes during mitosis |
| Metaphase | second phase of mitosis, during which the chromosomes line up across the center of the cell |
| Anaphase | the third phase of mitosis, during which the chromosome pairs separate and move towards opposite poles |
| Telophase | fourth and final phase of mitosis, during which the chromosomes begin to disperse into a tangle of dense material |
| Cytokinesis | division of the cytoplasm during cell division |
