All cells have a protective covering known as cell membrane. In plants, the cell membrane is further protected by another layer called cell wall. All the organelles present inside the cells are membrane bounded structure.
Cell membranes are made up of phospholipid bilayer with extrinsic and intrinsic proteins. From the studies on the plasma membrane structure, it was found that the protein fingerprint of MITOCHONDRIA and CHLOROPLAST are most similar to the cell membrane.
