| ATP | The high energy molecule used as an energy source by cells. |
| ADP | The lesser energy molecule that can be "recharged" into ATP |
| photosynthesis | plants use the energy of sunlight to convert water and carbon dioxide into oxygen and high-energy carbohydrates (sugars and starches) |
| chlorophyll | the principal pigment of plants and other photosynthetic organisms, light energy |
| Chloroplast | the organelle where photosynthesis takes place in plant cells. |
| White light | Contains all the wavelengths of light (colors) in the visible spectrum |
| Red and Blue light | The two colors of light absorbed the most by chloroplyll |
| Green light | One color chlorophyll does not absorb |
| light-dependent reactions | Reactions of photosynthesis that use energy from light to produce ATP. |
| light-independent reactions | Reactions of photosynthesis in which energy from ATP is used to build glucose from carbon dioxide. |
| Calvin Cycle | A set of Light Independent reactions that produces glucose using CO2, ATP and NADPH |
| Stoma | Small holes on the bottom side of a leaf where gases enter and exit |
| Palisade Mesophyll | The layer of cells in a leaf that contain chloroplasts, the site of photosynthesis |
| Spongy Mesophyll | The layer of cells in a leaf with air spaces that trap gases |
| Carbon Dioxide and Water | The reactants of Photosynthesis |
| Glucose and Oxygen | The products of Photosynthesis |
