Cell Cycle
| Term | Definition |
|---|---|
| interphase | phase before mitosis; growth of cell and preparation for division |
| prophase | chromatin condenses into chromosomes, nuclear envelope disappears, spindle fibers start to form |
| metaphase | chromosomes line up in the middle of the cell |
| anaphase | the sister chromatids seperate into individual chromosomes and are moved apart |
| telophase | chromosomes return to chromatin; nuclear membranes form; cleavage furrow begins |
| cytokinesis | splitting of the cytoplasm |
| mitosis | splitting of the nucleus |
| sister chromatids | Replicated forms of a chromosome joined together by the centromere and eventually separated (separation happens during anaphase!) |
| centromere | area on a chromosome connecting sister chromatids |
| spindle fibers | microtubules that extend from the centrioles and guide chromosome movement |
| nucleus | organelle that initiates cell division |
| cell plate | forms in plant cells to form new cell membrane and cell wall |
