Answer:
The light-dependent reactions take place in the thylakoid membranes in the granum (stack of thylakoids), within the chloroplast. Figure: The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions).
Explanation:
Each stack is called a granum (the plural is grana) which is suspended in a fluid called stroma. The light-dependent reactions occur in the grana; the light-independent reactions take place in the stroma of the chloroplasts.
