Answer:
The correct answer is option a. Membranes; chloroplast.
Explanation:
Photosynthesis is the process is specific to green plants and other photosynthetic organism converting light energy into storage energy by forming glucose from carbon dioxide and water and oxygen released as a byproduct.
This process involves the green pigment present in the plants called chlorophyll located in the chloroplast. The chloroplast is a double membrane organelle present in green plants. The membranes of the chloroplast are the site of photosynthesis.
Thus, the correct answer is option a. Membranes and chloroplast
