उत्तर
| Action Spectrum | Absorption Spectrum | |
| 1. | The curve that shows the rate of photosynthesis at different wavelengths is called action spectrum. | The curve which shows the amount of light absorbed by pigments at each wavelength is termed as absorption spectrum |
| 2. | It explains the relationship between photosynthetic activity in relation to different wavelengths of light. | It explains the relationship between quality of light and absorbing capacity of the pigments. |
| 3. | In action spectrum, the rate of photosynthesis is measured as amount of CO2 fixation, oxygen production, NADP+ reduction. | In absorption spectrum, absorption of different wavelengths of light pigments can be measured by spectrophotometer. |
