An absorption spectrum indicates the relative amount of light absorbed across a range of wavelengths. The graphs above represent the absorption spectra of individual pigments isolated from two different organisms. One of the pigments is chlorophyll a, commonly found in green plants. The other pigment is
bacteriorhodopsin, commonly found in purple photosynthetic bacteria. The table above shows the approximate ranges of wavelengths of different colors in the visible
light spectrum
(a) Identify the pigment (chlorophylla or bacteriorhodopsin) used to generate the absorption spectrum in each of the graphs above. Explain and justify your answer
