The fluid mosaic model of the cell

• The cell membrane is about 7nm thick
• It consists of a continuous phospholipid bilayer in which proteins are scattered in a mosaic manner.
• Proteins penetrate through the bilayer at a varying degree to form intrinsic and extrinsic proteins
• Intrinsic proteins are those that penetrate through the bilayer while extrinsic proteins are those that float on top as islands in a sea.
