Diagram and label the internal structure of a chloroplast. Briefly describe the function of each structure
you labeled. What will be an ideal response?
The diagram should be similar to Fig. 9-4b except no need to include the inner and outer membranes
because the question asks for internal structures. Functions include 1) thylakoid membrane/granum =
location of photosynthetic pigments and light-dependent reactions, 2) thylakoid lumen = establishment
of proton gradient for chemiosmosis, 3) stroma = location of enzymes for the Calvin cycle
