Photosynthesis
| Question | Answer |
|---|---|
| Chloroplasts | Organelle where photosynthesis takes place |
| Autotroph | an organism that makes its own food through the process of photosynthesis or chemosynthesis |
| ATP and NADPH | energy molecules created in the light-dependent phase - sent to the light-independent phase |
| Thylakoid | small discs within the chloroplast where light is absorbed by chlorophyll and begins the light-dependent reaction |
| Photosynthesis | The process where autotrophs convert light energy into chemical energy (glucose) |
| Factors affecting the rate of photosynthesis | light intensity, temperature, CO2 levels, availability of water |
| C6H12O6 | The chemical formula for glucose, the product of photosynthesis that is used for energy |
| 6CO2 + 6H2O -----------> C6H12O6 + 6O2 | The overall chemical formula for the process of photosynthesis |
| O2 Oxygen | The product of the light-dependent reaction that is released and no longer used within the process. |
| CO2 Carbon Dioxide | The reactant of photosynthesis that comes from the atmosphere and is used in the light-independent phase to make glucose. |
| H2O Water | The reactant of photosynthesis that comes from the soil through the roots and is used to eventually make ATP and NADPH energy molecules |
| Sunlight | The original energy source for all producers within an ecosystem. |
| Stroma | The substance and area in the chloroplast where the light-independent reaction takes place. |
| Light-dependent reaction | Used to capture light energy and transfer chemical energy (ATP and NADPH) to the light-independent reaction. |
| Chlorophyll a | The main pigment and substance that absorbs light within the thylakoid. |
| Accessory Pigments | Pigments like carotenoids that assist in absorbing energy that chlorophyll doesn't.....what you see in the Fall |
| Chromatography | A technique used to separate pigments from one another |
| Light-independent reaction | Chemical energy from the light-dependent reaction and CO2 from the atmosphere are used to create glucose |
| Heterotroph | an organism that cannot make its own food, and obtains nutrients through other sources of organic carbon |
