When comparing the absorption spectra of individual pigments to the overall action spectrum of a leaf, why is the action spectrum broader?
Q1. When comparing the absorption spectra of individual pigments to the overall action spectrum of a leaf, why is the action spectrum broader?
Answer: Overlapping absorption of various pigments
Explanation: Multiple accessory pigments absorb different wavelengths, making the action spectrum broader than any single absorption spectrum. Leaf thickness affects light quantity.
