| photosynthesis | the biochemical process that transforms light energy into chemical energy stored in glucose |
| autotrophs | organisms that can use light or chemical energy to make their own food |
| heterotrophs | organisms that are unable to make their own food and must consume other organisms |
| chlorophyll | green pigment that can absorb light energy |
| chloroplasts | organelles in plants that carry out photosynthesis |
| thylakoid membrane | coin shaped folds (grana) of inner membrane; the place where light dependent reactions take place |
| light dependent reactions | the stage of photosynthesis that requires the input of light energy and water and produces oxygen |
| stroma | liquid filled space between stacks of grana where light independent reactions take place |
| light independent reactions | the stage of photosynthesis where light energy is not needed and carbon dioxide is used to make molecules of glucose |
| ATP | the molecule used by cells to store and then release tiny amounts of energy |
| NADPH | the molecules that can carry high energy electrons during the process of photosynthesis |
| carbon fixation | the process of taking carbon from carbon dioxide gas and using it to build sugars |
| photolysis | the process of using light energy to split a molecule of water into hydrogen ions, electrons, and oxygen gas |
| electron transport chain | the biochemical process that transfers high energy electrons from one membrane protein to another in photosynthesis |
| Calvin Cycle | the second stage of photosynthesis where the carbon from carbon dioxide is incorporated into a simple sugar |
| glucose | a simple sugar that is the key product of photosynthesis |
