These supramolecular aggregates are attached on the outer surface of the thylakoid or photosynthetic membrane. Phycobilisomes absorb light in the range of 450—650 nm with an overall quantum efficiency of almost 100%, Electron microscopic studies showed that phycobilisomes consist of two distinct structure parts: the core and the rods.展开更多
