What is the difference between action spectrum and absorption spectrum in photosynthesis?
| 1. | The action spectrum shows wavelengths used for oxygen evolution, while the absorption spectrum shows wavelengths that chlorophyll absorbs. |
| 2. | The action spectrum measures the rate of photosynthesis at different wavelengths, while the absorption spectrum measures the rate of respiration. |
| 3. | Both spectrums measure the same wavelengths of light used in photosynthesis. |
| 4. | The absorption spectrum indicates the overall health of the plant, whereas the action spectrum does not. |
