Along with plants and algae in which organisms can photosynthesis occur

The correct answer is bacteria, that is the cyanobacteria. Actually, the cyanobacteria are most numerable organisms that conduct photosynthesis, only it isn't easily noticeable because they're not easily visible like regular plants found everywhere. They are the only prokaryotic organisms with the ability to produce oxygen.
