What is The Accessory Pigments Found in Red Algea That Are Especially Good At Absorbing Blue Light?

The accessory pigments found in red algae that are particularly effective at absorbing blue light are called phycobilins, specifically phycoerythrin. These pigments allow red algae to capture light energy for photosynthesis, especially in deeper water where blue light penetrates more effectively. Phycoerythrin imparts a red color to the algae while enhancing their ability to utilize available light for energy production.
