| Question | Answer |
| Chromatin | The bundle of DNA and protein that make up a chromosome, inside of nucleus. |
| Chromosome | Tightly coiled bundle of DNA and protein made of 2 chromatids. |
| Chromatid | One half of a chromosome |
| Centromere | Center point where 2 chromatids connect. |
| Centriole | Organelle in prophase, releases spindle fibers. |
| Interphase | 98% of a cell's life is spent in this phase, cell is carrying out it's normal day functions, and chromatin is in nucleus. |

Prophase

|
Centrioles are made, nuclear membranes start to dissolve, spindle fibers appear from the poles of the cell, and chromatin becomes chromosomes. |
| Metaphase | Chromosomes line up in middle of cell, spindle fibers wrap around the centromere. |
| Anaphase | Spindle fibers begin to pull at the centromere of each chromosome till they separate. |
| Telophase | 2 nuclear membrane, nuclei, and nucleoli form around the chromatids. Chromatids start to uncoil to chromatin. |

Animal cells: The cytoplasm begins to split down the middle, and 2 daughter cells are formed. Plant cells: The cell grows in width and the Golgi Bodies secrete material to form a new cell wall, called a cell plate. New wall grows down center of cell splitting into two. |
