The similarity of the action spectrum of photosynthesis and the absorption spectrum of chlorophyll tells us that chlorophylls are the most important pigments in the process. The spectra are not identical, though, because carotenoids, which absorb strongly in the blue, play a role as well.

Chlorophyll - Wikipedia, the free encyclopedia
Chlorophyll is a green pigment found in most plants, algae, and cyanobacteria. Its name is derived from the Greek χλωρός ( chloros "green") and φύλλον ( phyllon "leaf"). Chlorophyll absorbs l...

I'm talking about the results for both chlorophyll a and b. One of our plants has both chlorophyll a and b peaking at totally different wavelengths than the other plants, so I just thought it would be cool to talk about the variance in chlo...
