Plants do indeed appear green, because they reflect that part of the light spectrum back to our eyes. The colors of the light spectrum that plants most benefit from are the blue and red ends of the spectrum.

I think that plants can also use UV light for photosynthesis, and that it works even better than normal white light. This would be of higher frequency than light visible to humans.

yes, plants do not absorb green light, they reflect it, which is why they appear green. i think ithe color they absorb most is near the blue end of the spectrum
