| 301255326 | Chemical Reaction | Change that takes place when two or more substances (reactants) interact to form new substances (products). |  | 6 |
| 301255327 | ATP | Chemical energy in cells. |  | 7 |
| 301255328 | Cell | Basic unit of life. |  | 8 |
| 301255329 | Organelle | Small structures within cells that perform specific functions (ex. mitochondria, nucleus, ER). |  | 9 |
| 301255330 | Chromatin | DNA in a more relaxed state before it becomes chromosomes. |  | 10 |
| 301255331 | Chromosomes | Structures in a cell that contain genetic information. |  | 11 |
| 301255332 | Cytoplasm | Everything inside a cell except the nucleus. |  | 12 |
| 301255333 | Prokaryote | Single celled microorganisms that lack a nucleus (ex. bacteria). |  | 13 |
| 301255334 | Eukaryote | Organism whose cells have a nucleus and organelles (ex. human cells) |  | 14 |
| 301255335 | Cell membrane | Boundary between the cell and its environment; allows materials to move into and out of the cell. It's like a plastic bag with very small holes. |  | 15 |

| 301255338 | Aerobic Process (aero=air) | Process that requires oxygen. Example: we need to breathe oxygen to run and exercise |  | 18 |
| 301255339 | Anaerobic Process (an=not aero=air) | Process that does not require oxygen. |  | 19 |
| 301255340 | Photosynthesis | Process by which plants use light, carbon dioxide, and water to produce oxygen and sugar. |  | 20 |
| 301255341 | Cellular Respiration (spir=to breathe) | Process by which plants and animals use oxygen and carbohydrates to produce carbon dioxide, water, and energy. |  | 21 |
| 301255342 | Fermentation | Process by which cells release energy in the absence of oxygen (ex. lactic acid or alcoholic). |  | 22 |
| 301255343 | Cell Cycle | Series of events that cells go through as they grow and divide; includes interphase, mitosis, and cytokinesis. |  | 23 |
| 301255344 | Interphase (inter=between, phase=time period) | Part of the cell cycle where the cell is growing; includes G1, S, and G2. |  | 24 |
| 301255345 | Cytokinesis | Complete separation of the 2 new cells resulting from mitosis. |  | 25 |
