| Term | Definition |
|---|---|
| C4 Pathway | a carbon-fixing process in which carbon dioxide is bound to a compound to form a four carbon intermediate |
| Stomata | openings in a leaf or a stem of a plant that enable gas exchange to occur |
| carbon fibers | the synthesis of organic compounds from carbon dioxide such as in photosynthesis |
| Calvin cycle | a biochemical pathway of photosynthesis in which carbon dioxide is converted into glucose using ATP |
| chemiosmosis | in chloroplast & mitochondrion a process which the movement of protons down their concentration gradient across a membrane is coupled to the synthesis of ATP |
| electron transport chain | a series o molecules found in the inner membranes of mitochondria & chloroplast through which electrons pass in process that causes protons to build up on one side of the cell membrane |
| primary electron acceotor | in chloroplast an acceptor of electrons lost from chlorophyll found in the thylakoid membrane |
| photosystem | in the thylakoid membranes of chloroplast, a cluster of chlorophyll. 3 other pigment that harvest light energy for the light reactions of photosynthesis |
| cartenoid | class of pigments that are present mostly in plants during photosynthesis |
| chlorophyll | gives plants green color, reacts with sunlight carbon dioxide and water to make carbohydrates |
| pigment | substance that gives another substance/mixture color |
| stroma | the solution in plants that surrounds thylakoids in chloroplast |
| granum | a stack of thylakoids in chloroplast |
| thylakoid | found within chloroplast, contains components for photosynthesis |
| chloroplast | organelle where photosynthesis occurs |
| light reactions | the reactions in photosynthesis which are caused by the absorption of light in photosynthesis with passage of electrons production of NADPH and oxygen gas. synthesis of ATP through chemiosmosis |
| heterotroph | an organism that obtains organic food molecules by eating other organisms |
| photosynthesis | The process by which plants, algae, some bacteria use sunlight, carbon dioxide & water to produce carbohydrates and oxygen |
| autotroph | an organism that produces it's own nutrients from inorganic substances or from the environment instead instead of consuming other organisms |
