Can the absorption spectrum of chlorophyll a be completely overlapped with the action spectrum of photosynthesis?

Step-by-step solution

The wavelengths at which there is maximum absorption by chlorophyll a, i.e., in the blue and the red regions, also shows higher rate of photosynthesis. Hence, we can conclude that chlorophyll a is the chief pigment associated with photosynthesis. Can you say that there is a complete one-to-one overlap between the absorption spectrum of chlorophyll a and the action spectrum of photosynthesis? No. Though chlorophyll is the major pigment responsible for trapping light, other thylakoid pigments like chlorophyll b, xant
