| A | B |
|---|
| Chromatin | Loose uncoiled form of DNA; found in interphase and telophase |
| Chromosomes | Condensed form of DNA; found only in mitosis |
| Centromere | Connects 2 chromatids together |
| Chromatid | Single copy of a chromosome |
| Sister chromatid | Two identical copies of a chromosome |
| Centriole | Organelle that organizes DNA during cell division |
| Spindle fibers | Protein threads that attach to chromosomes |
| Cell plate | Name of cytokinesis in plants |
| Cleavage furrow | Name of cytokinesis in animals |
| G1 | Period of cell/organelle growth |
| G2 | Phase where DNA duplicates |
| S | Last chance for cell growth |
| Prophase | Phase where nuclear membrane disappears; spindle fibers form; DNA condenses into chromosomes |
| Metaphase | Phase where chromosomes line on the metaphase plate |
| Anaphase | Phase where the chromosomes are pulled to opposite ends of the cell |
| Telophase | Phase where the nuclear membranes reform; DNA uncoils into chromatin; spindle fibers disappear |
| Cytokinesis | Phase where the cell splits into 2 new daughter cells |
| Metaphase plate | Area of the cell where the chromosomes line up |
