Unformatted text preview: Stomata structure will be observed in the laboratory. 3 . Chloroplasts Photosynthesis occurs in chloroplasts. Recall that the chloroplast has a double membrane with a series of internal stacked membranes. Light energy is captured by the photosynthetic pigments located on the special membranes in the chloroplast called thylakoids, which are folded into disk-shaped stacks called grana. The interior compartments of thylakoids serve as reservoirs for hydrogen ions (H + ) that are needed for producing ATP. The reactions of photosynthesis that are involved in the transformation of light energy to chemical energy are called the light-dependent reactions. The reactions needed to produce carbohydrates occur in the stroma region of the chloroplast. Enzymes are located in the stroma. These reactions are known as the Calvin-Benson cycle or light-independent reactions....
