Wall made of double membrane i.e. outer membrane and inner membrane numerous stack-like (piles) groups or grana (singular = granum) are interconnected by lamellae.
Sac like structures called thylakoids Placed one above the other constitut granum.
Inside of the chloroplast is filled with a fluid medium called stoma.
Function: chloroplasts are the seat of photosynthesis (production of sugar, from carbondioxide and water in the presence of sunlight).

The structure of chloroplast can be described as a double membrane bound organelle. the inner membrane is folded into finger like projections called cristae. inside the inner membrane lies the matrix of the chloroplast known as stroma. the chloroplast also has single membrane bound thylakoids having chlorophyll and thylakoids are arranged as stacks known as grana.

i hope that helps :)
