The absorption spectrum of chlorophyll a differs from the action
spectrum of photosynthesis. Explain this observation.
Expert Solution

Step 1
The absorption spectrum indicates the wavelength of light absorbed by each pigment like chlorophyll, while the action spectrum shows the total rate of photosynthesis exhibited by light at a different wavelength.
