The lipid bilayer molecules act as a barrier for the cell.

Explanation:

The lipid bilayer molecules act as a barrier by allowing only certain molecules/substances to pass through the bilayer and into the cell, vice versa. The lipid bilayer is composed of two "layers". One layer is the "head" part which is the circular part of the bilayer. This is the hydrophilic layer, meaning water-loving. The other layer is the "tail" part which is the "stringy" part of the bilayer. This is the hydrophobic layer, meaning water-hating.
