Greetings,

I'll add my two cents to an especially educational thread (shout-out to jhupp's response in particuliar!)

The photon absorbance capacity of the chlorophyll photosystems + antenna complexes (and the chemical reactions they drive) is surprisingly limited. The means that photosystems exposed to light are saturated far below the intensity of noonday sun and can't make use of any remaining light energy no matter what the wavelength. The fluorescence that jhupp mentioned is necessary because a plant would burn-out its photosystem if it tried to absorb the full energy flux of sunlight striking its chloroplasts.
