The outer membrane is not permeable to larger proteins. Intermembrane Space-It is usually a thin intermembrane space about 10-20 nanometers and it is present between the outer and the inner membrane of the chloroplast. Inner membrane-The inner membrane of the chloroplast forms a border to the stroma.
Membrane Bound Organelles. 1  The Nucleus is the largest organelle in a cell. 2  It contains a dense structure called the Nucleolus and is surrounded by the Nuclear Envelope, a structure composed of two membranes, seperated by fluid, which contain a number of nuclear pores that can allow relatively large molecules through. Found only in plants and some protoctists, Chloroplasts are responsible for Photosynthesis. 2  Chloroplasts contain two fluid separated membranes and the inner membrane is folded into a network of flattened sacs called Thylakoids that are stacked into Grana (one Granum, two Grana).
