Chloroplasts have a smooth outer membrane and an inner membrane that encloses a stroma, which is a gel-like substance. Inside the stroma are thylakoids, which are stacked in structures called grana; these thylakoids have a more textured appearance due to their folded, membranous nature. Overall, chloroplasts have a complex structure that combines smooth and folded elements, allowing them to efficiently carry out photosynthesis.
