| 6158193681 | Autotroph | an organism that obtains organic food molecules without eating other organisms or substances derived from other organisms. Autotrophs use energy from the sun or from the oxidation of inorganic substances to make organic molecules from inorganic ones. |  | 0 |
| 6158193682 | C3 plant | A plant that uses the Calvin cycle for the initial steps that incorporate CO2 into organic material, forming a three-carbon compound as the first stable intermediate. |  | 1 |
| 6158193683 | C4 plant | A plant that prefaces the Calvin cycle with reactions that incorporate CO2 into a four-carbon compound, the end product of which supplies CO2 for the Calvin cycle. |  | 2 |
| 6158193684 | CAM plant | A plant that uses crassulacean acid metabolism, an adaptation for photosynthesis in arid conditions, first discovered in the family Crassulaceae. Carbon dioxide entering open stomata during the night is converted into organic acids, which release CO2 for the Calvin cycle during the day, when stomata are closed. |  | 3 |
| 6158193685 | Carbon fixation | The initial incorporation of carbon from CO2 into an organic compound by an autotrophic organism (a plant, another photosynthetic organism, or a chemoautotrophic prokaryote). |  | 4 |
| 6158193686 | Cyclic electron flow | A route of electron flow during the light reactions of photosynthesis that involves only photosystem I and that produces ATP but not NADPH or oxygen |  | 5 |
| 6158193687 | G3P | The carbohydrate produced directly from the Calvin cycle. |  | 6 |
| 6158193688 | Heterotroph | An organism that obtains organic food molecules by eating other organisms or their by-products. |  | 7 |
| 6158193689 | Light reactions | The steps in photosynthesis that occur on the thylakoid membranes of the chloroplast and that convert solar energy to the chemical energy of ATP and NADPH, evolving oxygen in the process. |  | 8 |
| 6158193690 | Photophosphorylation | The process of generating ATP from ADP and phosphate by means of a proton-motive force generated by the thylakoid membrane of the chloroplast during the light reactions of photosynthesis. |  | 9 |
| 6158193691 | Carotenoid | any of a group of red and yellow pigments, chemically similar to carotene, contained in animal fat and some plants. |  | 10 |
| 6158193692 | Chlorophyll A | Chlorophyll a is a specific form of chlorophyll used in oxygenic photosynthesis. It absorbs most energy from wavelengths of violet-blue and orange-red light |  | 11 |
| 6158193693 | Chlorophyll B | Chlorophyll b is a form of chlorophyll. Chlorophyll b helps in photosynthesis by absorbing light energy. It is more soluble than chlorophyll a in polar solvents because of its carbonyl group. Its color is yellow, and it primarily absorbs blue light. | | 12 |
| 6158193694 | CAM (Crassulacean acid metabolism) | a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions. In a plant using full CAM, the stomata in the leaves remain shut during the day to reduce evapotranspiration, but open at night to collect carbon dioxide (CO2). |  | 13 |
| 6158193695 | Mesophyll | the inner tissue (parenchyma) of a leaf, containing many chloroplasts. |  | 14 |
| 6158193696 | Photoautotroph | capable of synthesizing their own food from inorganic substances using light as an energy source. Green plants and photosynthetic bacteria are photoautotrophs. |  | 15 |
| 6158193697 | Photon | a discrete quantity of light energy |  | 16 |
| 6158193698 | Photosynthesis | the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct. |  | 17 |
| 6158193699 | Photosystem I | the mechanism that uses chlorophyll a (P700) to trap sunlight |  | 18 |
| 6158193700 | Photosystem II | the mechanism that uses chlorophyll a (P680) to trap sunlight |  | 19 |
