-Chloroplast
Explanation;
-Chloroplast is an organelle that is found in plants, which acts as a site for the process of photosynthesis, a process by which plants use energy from ssun light to make their own food.
-The organelle contains a double membrane (the inner and the outer membrane). The inner membrane surrounds the stroma and the grana (stacks of thylakoids). The chloroplast also contains a special pigment called chlorophyll that is responsible for trapping light which is used to split water molecules in the light dependent stage.
