Chloroplast thylakoids. Transmission electron micrograph (TEM) of a section through a chloroplast in a cell from a Coleus blumei plant, showing the stacked thylakoids (dark lines) that make up the grana. Chloroplasts are the site of photosynthesis in plant and algae cells. Thylakoids are membrane-bound compartments inside chloroplasts where the light-dependent reactions of photosynthesis occur.
