Question

Quizplus · Accepted Answer

Anoxygenic phototrophs use hydrogen sulfide or organic compounds as a source of electrons for photosynthesis, unlike oxygenic phototrophs that use water. They do not produce oxygen like oxygenic phototrophs. While some anoxygenic phototrophs contain a form of chlorophyll, it is not the same as the chlorophyll found in terrestrial plants.
