Verified step by step guidance

Understand that the plasma membrane is a crucial component of cells, providing structure and regulating the movement of substances in and out of the cell.

Recognize that the primary structure of the plasma membrane is the phospholipid bilayer, which consists of two layers of phospholipids. Each phospholipid molecule has a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails.

Identify that proteins are embedded within this phospholipid bilayer. These proteins can be integral (spanning the membrane) or peripheral (attached to the surface), and they play roles in transport, communication, and structural support.

Note that cholesterol is also present within the plasma membrane, providing fluidity and stability, but it is not a primary structural component like phospholipids and proteins.

Conclude that the correct components forming the structure of the plasma membrane are phospholipids and proteins, as they are essential for its function and integrity.
