Explanation:

The cell membrane (plasma membrane) has key functions: it acts as a selective barrier, controlling the entry and exit of substances (like nutrients, ions, and waste) into and out of the cell. It also helps maintain cell structure, facilitates cell - cell communication, and participates in processes such as cell signaling and adhesion. For example, it allows oxygen and glucose to enter the cell while preventing harmful substances from freely entering, and it can receive signals from other cells to regulate the cell's activities.

Answer:

The cell membrane functions as a selective barrier that regulates the passage of substances (e.g., nutrients, waste, ions) in and out of the cell, maintains cell structure, enables cell - cell communication, and participates in cell signaling and adhesion.
