Photosystem I -- An Intermediate Step -- May Not Be Necessary For Plants

.... "This is speculation, but this could be a crude prototype of primordial photosynthesis." Wanting to know whether these organisms really lacked the PSI complex, or whether it was working undetected, the researchers investigated a key protein in the PSI complex before and after the experiments. Owens was not...
