| Question | Answer |
| photosynthesis | converts solar energy into chemical energy of a carbohydrate |
| autotrophs | they produce their own food |
| heterotrophs | consumers |
| small holes in the leafs | Stomata |
| chlorplasts | the organelle that carry on photosynthesis |
| Stoma | semi fluid around the chloroplast |
| Flattened sacs | thylakoids |
| grana | stacked thylakiods |
| Chlorophyll | pigment in plants; absorbs violet-blue/red light: reflects green light |
| light reactions | photosynthesis using solar energy from the sun in the daytime |
| Calvin cycles | light- independent reaction- carbon fixation; synthesizes organic molecules from CO2 in air and energy in ATP?NADPH; not need light to work takes place in the stroma |
| mesophyll | thick layer of cells rich in chloroplasts |
| Chlorophyll A | main photosynthetic pigment; only pigment that can directly convert light to chemical energy |
| Chlorophyll B | secondary light- absorbing pigment; can absorb wavelengths that chlorophyll alpha can't |
| Carotenoids | absorbs wavelenths not efficiently absorbed bt chlorophyll |
| porphyrin ring | ring structure w/ alternating single/double bonds with MG atom in middle; energy channeled though carbon-bond system |
| action spectrum | relative effectiveness of different light wavelengths on photosynthesis |
| photoefficiency | high absorption efficiency leads to ability to absorb only a narrow bands of light |
