| 3154957449 | photosynthesis | The process by which plants, algae, and some protists and prokaryotes convert light energy to chemical energy that is stored in sugars made from carbon dioxide and water. | 0 | |
| 3154957450 | autotroph | An organism that makes its own food (often by photosynthesis), thereby sustaining itself without eating other organisms or their molecules. Includes plants, algae, and numerous bacteria. | 1 | |
| 3154960324 | photoautotroph | An organism that obtains energy from sunlight and carbon from CO2 by photosynthesis. | 2 | |
| 3154970239 | heterotroph | An organism that obtains organic food molecules by eating other organisms or substances derived from them; a consumer or a decomposer in a food chain. | 3 | |
| 3155050892 | chlorophyll | A green pigment located within the chloroplasts of plants algae and in the membranes of certain prokaryotes. | 4 | |
| 3155053781 | mesophyll | Leaf cells specialized for photosynthesis; a leaf's ground tissue system. | 5 | |
| 3155056803 | stoma | A microscopic pore surrounded by guard cells in the epidermis of a leaf. | 6 | |
| 3155070321 | stroma | The dense fluid within the chloroplast that surrounds the thylakoid membrane and is involved in the synthesis of organic molecules form carbon dioxide and water. Sugars are made here by the Calvin cycle. | 7 | |
| 3155070322 | thylakoid | A flattened membranous sac inside a chloroplast. Thylakoid membranes contain chlorophyll and the molecular complexes of the light reactions of photosynthesis. A stack is called a granum. | 8 | |
| 3155303382 | light reactions | The first of two stages in photosynthesis; the steps in which solar energy is absorbed and converted to the chemical energy of ATP an NADPH, releasing oxygen in the process. | 9 | |
| 3155307429 | NADP+ | Nicotinamide adenine dinulceotide phosphate, an electron acceptor that, as NADPH, temporarily stores energized electrons produced during the light reactions. | 10 | |
| 3155312228 | Calvin cycle | The second of two stages of photosynthesis; a cyclic series of chemical reactions that occur in the stroma of a cholorplast, using the carbon in CO2 and the ATP and NADPH produced by the light reactions to make the energy-rich sugar molecule G3P. | 11 | |
| 3155315696 | carbon fixation | The incorporation of carbon from atmospheric CO2 into an organic compound. | 12 | |
| 3155384928 | wavelength | The distance between crests of adjacent waves, such as those of the electromagnetic spectrum. | 13 | |
| 3155386727 | electromagnetic spectrum | The entire spectrum of electromagnetic radiation ranging in wavelength from less than a nanometer to more than a kilometer. | 14 | |
| 3155424586 | photon | A fixed quantity of light energy. The shorter the wavelength of light, the greater the energy. | 15 | |
| 3155424587 | photosystem | A light-capturing unit of a chloroplast's thylakoid membrane, consisting of a reaction-center complex surrounded by numerous light-harvesting complexes. | 16 | |
| 3155551003 | photophosphorylation | The production of ATP by chemiosmosis during the light reactions of photosynthesis. | 17 |
