| Heterotroph | Organism that obtains food by consuming other living things; also called consumers. |
| Photosynthesis | Process used by plants and other autotrophs to capture light energy and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energy-rich carbohydrates such as sugars and starches. |
| Calvin cycle | Light-independent reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugar. |
| Light dependent reactions | Set of reactions in photosynthesis that use energy from light to produce ATP and NADPH. |
| Chloroplast | Organelle found in cells of plants and some other organisms that capture the energy from sunlight and converts it into chemical energy. |
| Thylakoid | Saclike photosynthetic membranes found in chloroplasts. |
| Stroma | Fluid portion of the chloroplast; outside of the thylakoids. |
| Chlorophyll | Principal pigment of plants and other photosynthetic organisms. |
