| 3. Chloroplast: | An organelle found in plant and algae cells where photosynthesis occurs. |
| 4. Thylakoid: | A membrane system found within chloroplasts that contains the components for photosynthesis. |
| 5. Granum: | A stack of thylakoids in a chloroplast |
| 6. Stroma: | In plants, the solution that surrounds the thylakoids in a chloroplast |
| 7. Chlorophyll: | A green pigment that is present in most plant cells, that gives plants their characteristic green color, and that reacts with sunlight, carbon dioxide, and water to form carbohydrates. |
| 8. Carotenoid: | A class of pigments that are present in the thylakoid membrane of plants and that aid in photosynthesis |
| 9. Calvin Cycle: | A series of enzyme-assisted chemical reactions that produces a three-carbon sugar. |
| 10. Carbon Fixation*: | The incorporation of carbon atoms from CO in the atmosphere are bonded into organic compounds. |
