It is therefore an exergonic Process. Photosynthesis is Carbon. Photosynthesis And Cellular Respiration Venn Diagram Photosynthesis And Cellular Respiration Cellular Respiration Photosynthesis Respiration is the process done by around every of the living organism in both the green or non-green cells whereas photosynthesis is the food making process which only takes in chlorophyllous cells plants and other such livings. . It takes place in all the living cells of plant. The upcoming discussion will update you about the differences between Photosynthesis and Respiration. Photosynthesis happens in the chloroplasts and takes in energy whereas Respiration happens in Mitochondria and energy is released in this process. They do share one big similarity and that is that the process of photosynthesis is actually the same process only it is completed in reverse. It is a catabolic process in which complex organic foods are oxidized o
