Chloroplast measure 2um- 5um in diameter. It is a double membrane structure. The outer membrane is smooth while the inner membrane takes the form of stacks of coins called the thylakoid membrane. The thylakoid membrane is divided into coin like structures called grana. The area between the thylakoid and outer membrane is called the stroma.

Chloroplasts have 3 membranes: the outer membrane, the inner membrane, and the thylakoid membranes which are the innermost membranes. The outer and inner membranes are relatively smooth. The thylakoid membranes are individual stacks which are interconnected. A stack of thylakoids is called a granum. More than one granum are grana.

For a great picture.

Any diagram I have ever seen just refers to the two membranes as the outer membrane and the inner membrane. If it has another name, I've never seen it. But then I'm a zoologist, not a botanist.
