Question:
The capture of light involves the use of photosynthetic pigments because they absorb
photons. WHile the pigments used in photosynthesis absorb some wavelenths, they
relflect green wavelengths, which is whywe see green when looking at a plant. My
favorite pigment, red, would reflect wavelenths of light
Answer:
red
