| A | B |
| Photosynthesis | Using energy from sunlight to produce sugars |
| Light Reactions | Process of photosynthesis energy from light is captured and harnessed |
| Calvin Cycle | Process of photosynthesis that uses energy to build sugars |
| Chloroplast | Organelle which is the site of photosynthesis |
| Thylakoid | Internal membrane that contains cell pigments; site of light reactions |
| Stroma | Inner fluid of chloroplasts |
| Chlorophyll | Main pigment of photosynthesis |
| Photosystem I | 2nd stage of light reactions, electron carriers are produced |
| Photosystem II | 1st stage of light reactions, water is required. |
| NADPH | Electron carrier of photosynthesis |
| Ribulose Bisphosphate | First molecule of Calvin cycle, bonds with carbon dioxide |
| Reduction | Process of an atom/molecule gaining an electron |
| Oxidation | Process of an atom/molecule losing an electron |
| Glucose | Main sugar of cell respiration |
| Sucrose | Sugar used by plants for carbohydrate transportation |
| Starch | Sugar used by plants for storing in root systems |
| Cellulose | Sugar used by plants as a component of cell walls |
| Fatty Acids | Part of a lipid used by plants for forming oils |
| Chemiosmosis | Using a concentration gradient to build ATP molecules |
| Stomata | Gaps in plant leaves and stems where CO2 and H2O can pass |
| C3 Plants | Category of plants that collect CO2 through stomata |
| C4 Plants | Category of plants that pump CO2 into chloroplasts manually |
| CAM Plants | Category of plants that store CO2 at night for photosynthesizing |
