Question

Quizplus · Accepted Answer

The plasma membrane is composed of a phospholipid bilayer that surrounds the cell. This structure provides a barrier for the cell, allowing it to control the movement of molecules in and out of the cell. The phospholipid bilayer is made up of two layers of phospholipid molecules, with their hydrophilic heads facing outward and their hydrophobic tails facing inward. Other molecules, such as proteins and cholesterol, are also embedded in the membrane, giving it additional structure and function.
