Identify labelled structures in the diagram of chloroplast ____.
1=Outer membrane, 2= Inner membrane, 3= Grana, 4= Thylakoids, 5= Stroma
Two membranes contain and protect the inner parts of the chloroplast. They are appropriately named the outer and inner membranes. The inner membrane surrounds the stroma and the grana (stacks of thylakoids). One thylakoid stack is called a granum.
