Problem:

I always hear the pseudo-evolutionary claim "plants are green because they need to use red and blue light".

Required:

Question: What (if any) other functional relationship occur between the color of the blossom of the flower or the color of the leaves in the fall, and the spectrum of the sun.

Question: Could it be said that plants are actively absorbing a particular spectrum for a particular purpose by expressing particular colors other than green?Explain thoroughly.
