In prokaryotes, photosynthesis occurs on the folds of the cell membrane, which are called mesosomes. These mesosomes increase the surface area of the cell membrane, allowing for more photosynthetic pigments to be embedded in the membrane and more efficient photosynthesis to occur. In contrast, eukaryotes have specialized organelles called chloroplasts, which are responsible for photosynthesis. Chloroplasts have a double membrane and contain their own DNA, allowing them to carry out photosynthesis independently. The thylakoid membranes within the chloroplasts contain the photosynthetic pigments and are responsible for the light-dependent reactions of photosynthesis. Therefore, the locations where photosynthesis occurs differ in prokaryotes and eukaryotes, with prokaryotes utilizing the cell membrane and eukaryotes utilizing specialized organelles called chloroplasts.
