Plasma membranes enclose the borders of cells, but rather than being a static bag, they are dynamic and constantly in flux. 2021-01-19 The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell. 2020-09-22 Protection: It protects the cell from its surroundings or extracellular environment.

2021-04-15 Cell membrane overview and fluid mosaic model.
As a thin, semi-permeable substance, the cell membrane lets some things pass through into the cell while keeping others out. The cell membrane is extremely important for keeping the cell safe. Function of a Cell Membrane The cell or plasma membrane is meant to protect the cell from its outside environment, while also giving the cell structure and regulating the materials that enter and leave the cell.
