Both variations of Chlorophyll ,Chlorophyll a and Chlorophyll b, are effective photoreceptors because they contain a network of alternating single and double bonds, and the orbitals can be delocalized, which stabilizes the structure. Such delocalized molecules have very strong absorptions bands in the visible regions of the spectrum, allowing the plant to absorb energy from the sunlight. The light absorbed comes from the blue and red... Show More
