| KINGDOM OXYPHOTOBACTERIAE | |||||
These organisms use water as the electron donor in photosynthesis thereby releasing oxygen as a waste product. They all use chlorophyll A and the Chloroxybacteria also use Chlorophyll B in their photosynthetic machinery. Indeed, ultrastructural and molecular evidence suggest that they gave rise to chloroplasts through endosymbiosis. They can be complex in their growth form and many are very large. This kingdom has two phyla.
