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.
Cell wall and chloroplasts. These are only found in plant cells. Chloroplasts will be discussed in photosynthesis-but, like the mitochondria-they have an envelope of two membranes making up the outer wall. They have pairs of membranes called thylakoids arranged in stacks, each stack being called a granum.ER looks rough on the surface because it is studded with very small organelles called ribosomes. Ribosomes are made of RNA and protein and are the site of protein synthesis (see DNA and Genetic Code). There may be free ribosomes in the cytoplasm as well, which also are the site of protein synthesis.
