Hello everyone. And in today's video we have a problem stating oxygen. IQ photosynthesis releases oxygen as a byproduct. Which one of the following groups of organisms carry out oxygen in photosynthesis. So before we jump straight into our answer choices as quickly consider the types of photosynthesis and an organism can perform depending on their environment. So we have oxygen in photosynthesis which is usually performed by aerobic organisms. And this involves the using of water as a protein source. So the water molecule is going to be split and the hydrogen ions coming from it are going to be used as a protein source for for the synthesis. And this is usually performed by photosynthetic creates such as plants and augie and also by cyanobacteria. Now we also have an oxygen in photosynthesis which is a process more suited for organisms are anaerobic organisms that cannot be in the princess of oxygen. So they use hydrogen sulfide instead and they will do the same process of splitting this water, this hydrogen sulfide molecule and using the hydrogen coming from it as a pro tensors for photosynthesis. This is usually performed by most photosynthetic precarious except by cyanobacteria. Now what we really need to care about here is these organisms that are able to perform oxygen in photosynthesis which we said are photosynthetic bacteria and cyanobacteria. The only answer choice that contains only photosynthetic chariots and cyanobacteria is answer choice. C which are photosynthetic eukaryotes are going to be plants and algae and or cyanobacteria will be your last oxygen organism. And so that is the answer to our question. I really hope it helped you, and I hope to see you on the next video.
