The barrier between the intracellular and extracellular fluid compartments in an animal or plant is the <u>plasma membrane</u><u>.</u>
The plasma membrane or cell membrane is a double membraned cell organelle that surrounds and protects the cell and other cell organelles. Both prokaryotic and eukaryotic cells have a cell membrane.
The plasma membrane is about 5 - 8 nm in thickness and is composed of proteins, lipids and carbohydrates that come together to form a flexible bilayer. This lipid bilayer gives the cell membrane its ability to separate intracellular and extracellular fluids.
The plasma membrane also plays a role in signalling and communication between cells and anchors the cytoskeleton to provide cell shape and maintain cell potential.
