Description
Chloroplasts are double-membraned organelles with an outer membrane and an inner membrane. Inside the chloroplast, there is a fluid-filled space called the stroma, where various enzymes and molecules necessary for photosynthesis are located. Embedded within the stroma are stacks of membrane-bound structures called thylakoids. These thylakoid stacks are known as grana (singular: granum). Chlorophyll molecules are embedded in the thylakoid membranes and are responsible for capturing light energy during photosynthesis.
