Answer:
The plasma membrane protects the cell from its external environment, mediates cellular transport, and transmits cellular signals.
Learning Objectives
Describe the function and components of the plasma membrane
Key Points
The principal components of the plasma membrane are lipids ( phospholipids and cholesterol), proteins, and carbohydrates.
The plasma membrane protects intracellular components from the extracellular environment.
The plasma membrane mediates cellular processes by regulating the materials that enter and exit the cell.
The plasma membrane carries markers that allow cells to recognize one another and can transmit signals to other cells via receptors.
Key Terms
plasma membrane: The semipermeable barrier that surrounds the cytoplasm of a cell.
receptor: A protein on a cell wall that binds with specific molecules so that they can be absorbed into the cell.
Structure of Plasma Membranes
The plasma membrane (also known as the cell membrane or cytoplasmic membrane) is a biological membrane that separates the interior of a cell from its outside environment.
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells. Plasma membranes must be very flexible in order to allow certain cells, such as red blood cells and white blood cells, to change shape as they pass through narrow capillaries.
