The General Functions of the Plasma Membrane Include ________

Question

The general functions of the plasma membrane include ________.
A) physical isolation of the cell contents from the surrounding extracellular fluid
B) regulation of exchange of materials with the environment
C) sensitivity to changes in the extracellular fluid
D) structural support of the cell
E) All of the answers are correct.

Accepted Answer

All of the answers are correct. The plasma membrane acts as a physical barrier that separates the cell's contents from the surrounding extracellular fluid. It regulates the exchange of materials, allowing some substances to enter and exit the cell while preventing others from doing so. It is sensitive to changes in the extracellular fluid, enabling the cell to respond to its environment. Additionally, the plasma membrane provides structural support to the cell, helping to maintain the shape and stability of the cell.
