Chlorophyll is a pigment that absorbs specific wavelengths of light, and the absorption of that light leads to the passage of electrons to a higher energy state, where chemical energy can then be harvested from them. You would expect that a plant exposed to which color of light would produce the most photosynthesis?

green
orange
yellow
blue

Which color of light would you expect chlorophyll to absorb the least?

green
red
yellow
blue

Most plants are green because....

chlorophyll absorbs green light well
chlorophyll does not absorb green light well
chlorophyll reflects green light well
both of the last two answers are correct
