Final answer:
The components of a chloroplast are thylakoid membranes, stroma, and chlorophyll. The light-dependent reactions in photosynthesis occur in the thylakoid membranes of chloroplasts.
Step-by-step explanation:
Components of a Chloroplast:
Thylakoid membranes
Stroma
Chlorophyll
Location of the Light-Dependent Reactions:
The light-dependent reactions occur in the thylakoid membranes of chloroplasts. These reactions involve the absorption of sunlight by chlorophyll, which converts the energy into chemical energy and produces energy carriers like ATP and NADPH. These energy carriers then transfer the energy to the light-independent reactions that occur in the stroma of chloroplasts.
