How is oxygen created in photosynthesis
Web31 mei 2024 · Scientists confirmed van Niel’s hypothesis that oxygen released from photosynthesis comes from water with the use of 18O, a heavy isotope, as a tracer to follow the fate of oxygen atoms during photosynthesis. The experiments showed that the O2 from plants was labeled with 18O only if water was the source of the tracer.
