What is the significance that the combined absorption spectra of chlorophylls a and b roughly match the action spectrum of photosynthesis? Wouldphotosynthesis be more efficient if their individual absorption spectra coincided exactly?
What does this reveal about the role of the carbon dioxide in photosynthesis?
