Explanation:

The fluid - mosaic model describes the plasma membrane. The phospholipid bilayer forms the basic structure of the membrane and acts as a fundamental barrier separating the cell's internal and external environments. Membrane carbohydrates are mainly involved in cell - cell recognition and adhesion, and integral and peripheral proteins have functions like transport, signaling, etc. but do not form the basic barrier.

Answer:

The phospholipid bilayer
