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"?
