It is a theory proposed S.J. Singer and Garth Nicolson in 1972 to explain the properties of a cell membrane. 1. Cell membranes are made of 2 layers of phospholipids. 2. A phospholipid is a large molecule, based on a triglyceride. It has a phosphate head which is water-loving and a fatty acid tail which repels water. 3. The phosphate head forms the outside of the layer and attracts water. 4. The fatty acid is repelled by the water and points towards the middle of the molecule: http://upload.wikimedia.org/wikipedia/commons/f/f0/Lipid_bilayer_section.gif Molecule is a part of the mosaic. If you looked at the membrane from above, it would look like a mosaic of phospholipid. The 'Tiles' are not joined and have gaps between them. Google Phospholipid Bilayer for more info.
