The various reactions in photosynthesis are spatially segregated from each other within the chloroplast. Draw a simplified diagram of a chloroplast and include these parts: outer membrane, grana, thylakoid, lumen, stroma/matrix.

a. Where in the chloroplast do the light reactions occur?
b. Where in the chloroplast is the chemiosmotic gradient developed?
c. Where in the chloroplast does the Calvin cycle occur?
