Question
What can we conclude from the statement that the action and absorption spectrum of photosynthesis overlap? At which wavelength do they show peaks?
Solution
The wavelengths at which there is maximum absorption by chlorophyll a, i.e. in the blue and the red regions, also show a higher rate of photosynthesis. Hence, we can conclude that chlorophyll a is the chief pigment associated with photosynthesis.
The action spectrum of photosynthesis is superimposed on the absorption spectrum of chlorophyll a.
