Prokaryotes by definition lack such structures. How can bacteria carry out photosynthesis?
Algae and certain bacteria photosynthesize just as plants do, but they use a different set of mechanisms. Biochemically, photosynthesis is processed in the same way inside the organism; however, chlorophyll is not always the primary pigment that processes energy. In bacteria, the processes behind photosynthesis are a little different. Just as in algae, bacteria may depend on pigments in addition to chlorophyll to complete photosynthesis. However, completely unlike either plants or algae, photosynthesizing bacteria do not have chloroplasts. Their photosynthetic chemicals are loose in the cellular membrane, and can work from any point inside the bacteria. Cyanobacteria, which are blue in color, contain both chlorophyll and oxygen, and are closer than any other bacteria to plant-style photosynthesis; it is believed that plants evolved directly from cyanobacteria. Other photosynthetic bacteria contain different pigments referred to as bacteriochlorophylls, and they do not produce oxygen.
