- In photosynthetic eucaryotic cells, the photosynthetic membranes are found in the chloroplasts. The chloroplast has three membranes. The outer and inner membranes are similar in composition. The inner membrane is not convoluted. A third membrane, called the thylakoid membrane, is folded to make lamellae that are in turn stacked to make the grana. The colourless part of the chloroplast is called the stroma. Lamellae join different grana throughout the stroma.
