Unformatted text preview: just chlorophyll a? The absorption spectra of chlorophyll a and chlorophyll b are different, allowing a plant harvest the energy of a wider range of light photons for photosynthesis, but it is also critical that the energy captured from a photon that hits either type of chlorophyll can be transferred [by resonance] to the other type. So, even though only chlorophyll a is found in a photosystems reaction center, having both types of chlorophyll in the antenna complex allows the plant to harvest/use a wider range of photon energies/wavelengths/frequencies than it would it if just had chlorophyll a....
