| Question | Answer |
|---|---|
| Surface area to volume ratio | as the length of a cell increases its volume increases faster than its surface area. |
| Cell Division | the process by wich a cell divides forming two new "daughter" cells |
| Chromosome | made of DNA and proteins (which carry the cell's coded genetic infromation.) |
| Chromatin | consists of DNA tightly coiled around proteins, attached at the centromere |
| Chromatids | one of the identical sister parts of a duplicated chromosome. |
| Centromere | area where the chromatids of a chromosome are attached. |
| Cell Cycle(definition) | series of events that cells go through as they grow and divide. |
| The phases of the cell Cycle | Mitosis[=prophase, metaphase, anaphase, and Telophase] + cytokinesis = M phase (Cell Division). Chromosome synthesis = S phase G1 and G2 phase (interphase) |
| Interphase | period of the cell cycle between cell divisions. |
| Mitosis | part of the eukaryotic cell division during which the cell nucleus divides. |
| prophase | first phase, longest phase, chromosomes becomes visible, chromatin condenses into chromosomes |
| Metaphase | second phase, the chromosomes line up across the center of the cell. |
