 The pigments in the grass, including chlorophyll
 and others, are organized in the chloroplasts to
 efficiently absorb both high energy, short
 wavelength blue light, and lower-energy, longer
 wavelength red light (some from sunlight, and some
 "scavenged" from energy re-radiated by chlorophyll
 as red wavelengths).  Chlorophyll does not absorb
 the green wavelength light well, so the plant
 looks green from the reflected green light.
 Flowers aren't green because they have other
 pigments that absorb some light wavelengths and
 reflect the color of the blossom.
 
 Now, what is "mowing"? Does it have something to
 do with "Yard work"?
