i understand that the tails of the phospholipids are hydrophobic and form a barrier to water soluble substances (and supposedly not to water? ), therefor how can water pass though what is effectively a layer of oil? does water enter through channel proteins? can water pass through the cell membrane as it is a smaller molecule than say a substance that is dissolved in it?
