Membranes are effective barriers preventing the crossing of both polar and nonpolar molecules from one side to the other. Explain why it is difficult for any species to pass from one side of a membrane to the other, more specifically explain how membranes are able to keep polar molecules out of the cell, keep nonpolar molecules out of the cell and what region of the membrae the polar and nonpolar/ hydrophilic molecules will not like being assoicated with.

The structure and function of a cell is dependent on membranes. These membranes separate the interior of the cell from its environment and form the various internal compartments of the eukaryotic cells.
The membrane formation is based on lipids, and all cell membranes have a common structural organization: phospholipid bilayer with associated proteins.
