1. Protection: The cell membrane provides protection to the cell by acting as a barrier between the cell's internal environment and the outside world. It prevents harmful substances from entering the cell.

2. Selective Permeability: The cell membrane is selectively permeable, meaning it allows certain substances to pass through while blocking others. This helps in maintaining the balance of ions, nutrients, and other substances within the cell.

3. Transport: The cell membrane facilitates the transport of substances in and out of the cell. This can occur through passive transport (like diffusion or osmosis) or active transport (which requires energy).

4. Communication: The cell membrane contains receptors that allow the cell to communicate with other cells. These receptors can receive signals from other cells or the environment, and transmit these signals into the cell.

5. Attachment: The cell membrane provides sites for attachment for the cytoskeleton (which gives the cell its shape and aids in movement) and the extracellular matrix (which provides support and anchorage for cells).

6. Enzymatic Activity: The cell membrane also has enzymes that carry out specific chemical reactions. These enzymes can help in the breakdown of nutrients, the synthesis of new molecules, or the generation of energy.
