Photosynthetic pigments use primarily the visible light portion of the electromagnetic spectrum. Pigments found in chlorophyll absorb various portions of visible light; this is their absorption spectrum. Two major photosynthetic pigments are chlorophyll a and chlorophyll b. Both chlorophylls absorb violet, blue, and red wavelengths best.

An action spectrum is a graph that profiles the relative effectiveness of different wave-lengths of radiation in driving photosynthesis. The broader peaks observed in the action spectrum seen in Figure 10.9 can be explained by the presence of pigments other than chlorophyll that capture light energy in the chloroplast, such as carotenoids and ...
