The correct answer is: Stacks of membrane-bounded, flattened discoid sacs called thylakoids containing the molecules of chlorophyll.
Thylakoids are flattened sacs arranged like the stacks of coins. One stack of thylakoids is called a granum. Grana are stacks of membrane-bounded, flattened discoid sacs called thylakoids containing the molecules of chlorophyll. Granum is the site of the light reaction during photosynthesis. They are the main functional units of chloroplasts.
