| photosynthesis | process by which light energy is converted to chemical energy; produces sugar and oxygen from carbon dioxide and water |
| chlorophyll | light-absorbing pigment molecule in photosynthetic organisms. |
| thylakoid | membrane-bound structure within chloroplasts that contains chlorophyll and other light-absorbing pigments used in the light-dependent reactions of photosynthesis |
| light-dependent reactions | part of photosynthesis that absorbs energy from sunlight and transfers energy to the light-independent reactions |
| light-independent reacations | part of photosynthesis that uses energy absorbed during the light-dependent reactions to synthesize carbohydrates |
