Given graph represents the absorption specra of three photosynthetic pigments chl a, chl b and `beta`-carotene. Select the correct statement regarding this.A. The curve showing the amount of absorption of different wavelengths of light by a photosynthetic pigment is called as absorption spectrumB. chl a and chl b absorb maximum light in blue and red wavelengths of light.C. Rate of photosynthesis is maximum in blue and red wvelengths of light.D. All of these |
|
Answer» Correct Answer - D The graphical curve showing the amount of energy of different wavelengths of light absorbed by a pgment is called absorption spectrum,. It is studies with the help of spectrophotometer. The absorption spectra of chorophylls a and b show that they absorb maximum light in the blue-violet and red wavelengths. The pgments are often known after the wvelength which is absorbed to the maximum e.g., chl `a_(673)` Chl `a_(683)(P_(680)),` Chl `a_(703) (P_(700))`. |
