Final answer:
The membranes or compartments of the chloroplast are the outer membrane, inner membrane, thylakoid membranes, and stroma. The light reactions occur in the thylakoid membranes, and the Calvin cycle occurs in the stroma.
Step-by-step explanation:
The membranes or compartments of the chloroplast are:
- Outer membrane: Surrounds the entire chloroplast.
- Inner membrane: Located inside the outer membrane
- Thylakoid membranes: Neat stacks called grana, which contain sac-like membranes known as thylakoid membranes. These membranes contain photosystems and are the site of the light reactions of photosynthesis.
- Stroma: The space outside the thylakoid membranes where the reactions of the Calvin cycle take place.
The light reactions of photosynthesis occur in the thylakoid membranes, while the Calvin cycle occurs in the stroma.
