Structure of the plasma membrane (article) | Khan Academy
The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins. A phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group.

Cell membrane – Wikipedia
The cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates and protects the interior of a cell from the outside environment (the extracellular space).

The cell membrane review (article) | Khan Academy
The cell membrane contains a phospholipid bilayer, but the terms are not interchangeable. Part of the cell membrane is a phospholipid bilayer, made of two layers of phospholipid molecules. However, the cell membrane also contains other macromolecules like membrane proteins, and carbohydrates.

As the outer layer of your skin separates your body from its environment, the cell membrane (also known as the plasma membrane) separates the inner contents of a cell from its exterior environment. This cell membrane provides a protective barrier around the cell and regulates which materials can pass in or out.

Cell parts and functions (article) | Khan Academy
The cell membrane surrounds a cell’s cytoplasm, which is a jelly-like substance containing the cell’s parts. Cells contain parts called organelles. Each organelle carries out a specific function in the cell. A cell’s organelles work alone and together to keep the whole cell functioning. Mitochondria are organelles that break down sugars.

Finally, the membrane, or more precisely, the chemical gradients across the membrane, is an important energy source for the cell. 4.1: Membrane Structure and Composition. Since most cells live in an aqueous environment and the contents of the cell are also mostly aqueous, it stands to reason that a that separates one side from the …
