Do plants absorb 100% of the energy from the sun?

    By virtue of their coloration, plants do not absorb 100% of the energy from the sun for photosynthesis. If they could absorb it they would probably be black in color. It is kind of weird to think of that way, but imagine if you would that chlorophyll is green, period. That is because certain wavelengths of light are being reflected off of it. Those wavelengths are not being absorbed then. Also, if one were to consider that plants create waste products as well, then plants are not being 100% efficient at absorbing the sum total of the things that fuel them.

    Researchers indicate that plants are only at most 3-6% efficient at absorbing sun. The citation has more information on how efficient plants are at photosynthesis 🙂
