Quizplus · Accepted Answer

The lipid bilayer is composed of hydrophobic (water-repelling) tails that form the interior of the membrane and hydrophilic (water-attracting) heads that face the inside and outside of the cell. This arrangement creates a barrier to water-soluble substances, preventing them from freely diffusing across the membrane. Proteins and carbohydrates may be involved in other functions of the plasma membrane, but they are not primarily responsible for its barrier properties.
