The structure and function of the cell membrane.

Each cell is surrounded by a membrane. It can be single or double layer. The membrane consists of many proteins and phospholipids, which form a strong framework with different pores and channels. The membrane protects the cell from various influences and separates the contents of the cell from the environment.
