| Autotroph | organism that makes own organic compounds (food) |
| Photosynthesis | The process of using light to make carbohydrates |
| Heterotroph | Organisms that must consume other organisms to get organic compounds |
| Light Reactions | Part of photosynthesis where light and water are used to make ATP and NADPH |
| Calvin Cycle | Pt of photosynthesis that takes CO2 and energy in ATP/NADPH to make carbs |
| Chloroplasts | Organelles where photosynthesis takes place |
| Thylakoids | A system of membranes in a chloroplast where the light reactions take place |
| Grana | A stack of thylakoids |
| Stroma | A solution surrounding the grana where the Calvin Cycle occurs |
| Pigments | Compounds that absorb light |
| Chlorophylls | Major pigment in plants that absorb light during photosynthesis |
| Carotenoids | Accessory pigments in plants |
| Photosystem | A cluster of similar pigment molecules |
| Primary Electron Acceptor | Accepts the electrons lost from chlorophyll a |
| Electron Transport Chain | Gets electrons from the primary electron acceptor and is passed from one to another. |
| Chemiosmosis | Uses the energy of concentration gradient set up by the ETC to pump H+ into thylakoid |
| Carbon Fixation | Incorporating CO2 into organic compounds |
| Stomata | Openings on the underside of leaves to allow for CO2, H2O, and O2 to pass |
| C4 Pathway | Allows plants in hot climates to keep stomata partially open |
| CAM Pathway | Allows plants in hot climates to keep stomata closed during the day. |
