WebAnoxygenic Photosynthesis in Bacteria: Purple and green bacteria possess only photosystem I. Since they lack photosystem II, they cannot use water (H 2 O) as an electron donor in noncyclic photophosphorylation (i.e., noncyclic electron transport) and thus cannot produce oxygen from water photosynthetically, i.e., they are anoxygenic.
