Which of the Following Best Describes the Structure of the Plasma

Question

Which of the following best describes the structure of the plasma membrane?
A)The plasma membrane is a phospholipid bilayer surrounding the cell.
B)The plasma membrane is composed of cristae.
C)The plasma membrane is a double layer of protein enclosing the plasma.
D)The plasma membrane is a single-layered membrane that surrounds the nucleus of the cell.

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.
