Why is it important for a plant to have more pigments than just chlorophyll?
if the plant has more than one color of pigments, it can absorb more spectrums of the visible scale and create food longer, therefore surviving longer
If the plant only has chlorophyll, it is only able to absorb and use the wavelengths of light that correspond to chlorophyll, which is really limiting. Having other pigments allows it to use more wavelengths of light, which is more efficient.
