There are many differences between photosynthesis and cellular respiration. Photosynthesis requires energy as photons. Cellular respiration supplies energy in the form of ATP. In photosynthesis‚ electron transport occurs in the membranes of chloroplasts or thylakoid discs. Cellular respiration takes place in the membranes of mitochondria.
