Answer:
The correct answer is "thylakoids; stroma".
Step-by-step explanation:
The thylakoids are compartments located within the chloroplasts where absorption of light energy and movement of electrons occurs. The thylakoids have multiprotein complexes called photosystems that act as light receptors to perform these processes. On the other hand, the synthesis of carbohydrates occurs in the stroma, a colorless fluid inside of chloroplasts where the final steps of the photosynthesis occurs.
