| A | B |
| organism that can make its own glucose | autotroph |
| organism that has to obtain food | heterotroph |
| ultimate source of energy for all living things | sun |
| this organism both produces and releases oxygen | algae |
| this organism uses oxygen and releases carbon dioxide | bacteria |
| reactants of this reaction are oxygen and glucose | cellular respiration |
| products of this reaction are oxygen and glucose | photosynthesis |
| this pigment allows plants to carry out photosynthesis | chlorophyll |
| this type of cellular respiration requires oxygen to occur | aerobic |
| this type of cellular respiration doesn't require oxygen | anaerobic |
| the most important product of cellular respiration | ATP |
| a molecule that is able to store usable energy | ADP |
| the plant organelle that contains chlorophyll | chloroplast |
| a plant undergoes photosynthesis to make this product | glucose |
| this process makes ATP and alcohol without using oxygen | fermentation |
| this gas is needed to release energy from glucose | oxygen |
| when does cellular respiration occur in a plant | 24 hours a day |
| ATP | a usable form of energy |
| the process of photosynthesis | changes light energy to chemical energy |
