Answer:

The function of a cell membrane is to protect the cell from its surroundings, control the movement of substances in and out of the cell, and provide structural support.

The cell membrane, also known as the plasma membrane, is a vital component of any cell. It is a thin, semi-permeable membrane that surrounds the cytoplasm of a cell and separates the intracellular environment from the extracellular environment. The cell membrane plays several crucial roles in maintaining the integrity and function of a cell.

One of the main functions of the cell membrane is to protect the cell from its surroundings. It acts as a barrier that prevents harmful substances from entering the cell and protects the cell's internal environment. Additionally, the cell membrane plays a key role in controlling the movement of substances in and out of the cell. It regulates the passage of ions, nutrients, and other molecules to maintain the cell's homeostasis.

Furthermore, the cell membrane provides structural support to the cell. It helps to maintain the shape of the cell and provides stability to the cell membrane. The cell membrane is composed of lipids, proteins, and carbohydrates that work together to perform these functions efficiently.

In conclusion, the cell membrane is a crucial component of cells that plays a vital role in protecting the cell, regulating the passage of substances, and providing structural support. Understanding the importance of the cell membrane is essential in comprehending the functioning of cells and their survival.
