Explanation:

The cell - membrane is composed mainly of a phospholipid bilayer. It is selectively permeable, meaning it allows certain substances to pass through while restricting others. Proteins are embedded in or associated with the cell - membrane, but the main component is phospholipids. It is not impenetrable as substances can cross it, and being studded with proteins is not the main characteristic indicating its permeability property.

Answer:

selectively permeable
