Question 10

Explain the functions of the cell membrane.

Accepted Answer

The cell membrane, also known as the plasma membrane, serves several important functions in a cell.

First and foremost, the cell membrane acts as a barrier, separating the interior of the cell from the external environment. This barrier is crucial for maintaining the internal environment of the cell and protecting it from potentially harmful substances outside.

Additionally, the cell membrane is selectively permeable, meaning it allows certain molecules to pass through while blocking others. This selective permeability is essential for controlling the movement of substances in and out of the cell, which is necessary for maintaining the cell's internal balance and carrying out various cellular processes.

The cell membrane also plays a role in cell communication and recognition. It contains various proteins and receptors that allow the cell to interact with its environment and other cells. These interactions are important for processes such as cell signaling, immune response, and cell adhesion.

Furthermore, the cell membrane helps to maintain the cell's shape and structure. It provides support and stability to the cell, while also allowing for flexibility and movement.

Overall, the cell membrane is a vital component of a cell, serving as a protective barrier, regulating the passage of molecules, facilitating communication and recognition, and contributing to the cell's structure and function.
