AP Biology Photosynthesis Exam

What is one function of the other pigments  besides chlorophyll, in the chloroplast?

• to block damaging wavelengths of light
• to absorb different wavelengths than the chloroplasts
• to provide different colors to the leaves
• to transfer energy to a separate photosystem beside the one using chlorophyll a and b.
