structure summary
Phycobilisomes are light-harvesting antennae that transmit the energy of harvested photons to photosystem II and photosystem I in cyanobacteria and in the chloroplasts of red algae and glaucophytes.[1][2][3] They were lost during the evolution of the chloroplasts of green algae and plants.[3]
