| Centrioles | Provides a place of attachment for the spindle fibers in animal cells. |
| Spindle fibers | Move the chromosomes and chromatids around in the cell. |
| Chromatids | A half of a chromosome - each is an exact copy of the other. |
| Chromosome | Wound up DNA in a small packet |
| Centromere | Part of a chromosome which holds the chromatids together |
| Centromere | A part of a chromosome where the spindle fibers attach |
| DNA replication | How A,T,G, and C match up on a "unzipped" DNA strand to make a new copy. |
| Interphase | When DNA and organelle replication take place |
| Prophase | Teh DNA is winding up, the nuclear membrane and nucleolus break down |
| Metaphase | The chromosomes are lined up in the middle by the spindle fibers |
| Anaphase | The chromatids are pulled to opposite sides of the cell by spindle fibers |
| Telophase | New nuclear membranes are forming |
| Cytokinesis | Two new cells are forming |
| Cell plate | Plant cells form a new cell wall to have two cells |
| "Pinching" | How animal cells form two new cells. |
