Question

What is the advantage of a plant having multiple pigments?

Answer 1

Each pigment has its own characterisitic absorption spectrum or part of the total spectrum of the light that lands on a plant that gets absorbed by the photosynthesis action centres. Chlorophyll will reflect green light and absorb theother colours, so any of the light that has green wavelength characteristics would be wasted unless there was another colour that absorbs green light, like red pigment
