What are the pigment characteristics of red algae and cyanobacteria?

The pigments in algae are the most important part of photosynthesis. In both red algae and cyanobacteria the pigments are mostly phycobilins. These are water-soluble pigments, and are therefore found in the cytoplasm, or in the stroma of the chloroplast. They occur only in Cyanobacteria and Rhodophyta ( Red Algae)
