In the context of the lipid bilayer, what is another name for the cell membrane?
A
Cell wall
B
Endoplasmic reticulum membrane
C
Nuclear envelope
D
Plasma membrane
Verified step by step guidance1
Understand that the lipid bilayer is a fundamental structural component of certain cellular membranes.
Recall that the cell membrane, which surrounds the cell and controls the movement of substances in and out, is composed primarily of a lipid bilayer.
Recognize that the term 'plasma membrane' is another name for the cell membrane, emphasizing its role as the boundary between the cell's interior and its external environment.
Differentiate the plasma membrane from other membrane structures such as the cell wall (found in plants and bacteria), the endoplasmic reticulum membrane (internal membrane system), and the nuclear envelope (membrane surrounding the nucleus).
Conclude that the correct alternative name for the cell membrane, based on its lipid bilayer structure and function, is the plasma membrane.
