What accessory pigments found in red algae that are specially good at absorbing blue light are called?
Accessory pigments found in red algae that are good at absorbing blue light are called phycobiliproteins, specifically phycocyanin and allophycocyanin. These pigments help red algae efficiently capture and use blue light for photosynthesis in deep water environments where other wavelengths of light do not penetrate as effectively.
