Question

Why are blue and red efficient colours of light for photosynthesis, but green and yellow aren't?

(Please help. If possible please provide the most scientific answer as possible. Thank you!)

Answer 1

Answer:

Trees and plants are green because of a green pigment called chlorophyll. This pigment absorbs red light the best and converts the light into energy that it uses for metabolism. However, the pigment doesn't strongly absorb blue or green light, so plants can't use this energy for photosynthesis.
