In eukaryotic plants, photosyntesis takes place within the chloroplastes, and rispiration in the mitocondria. In prokaryotes such us bacteria, it is not necessary to have specific organells devoted to these function as, again, the cells are so small.
The term cellular respiration refers to the biochemical pathway by which cells release energy from the chemical bonds of food molecules and provide that energy for the essential processes of life. ... More emphasis here will be placed on eukaryotic cells where the mitochondria are the site of most of the reactions.
