Cell membrane. Specialized structure that surrounds the cell and its internal environment; controls movement of substances into/out of cell. Hydrophobic. Molecule that repels water (“water-fearing”) Hydrophilic. Molecule that is attracted to water (“water-loving”) Amphipathic. Molecule that contains both a hydrophobic and a hydrophilic end.

The biological model, which was devised by Seymour Jonathan Singer and Garth L. Nicolson in 1972, [1] describes the cell membrane as a two-dimensional liquid that restricts the lateral diffusion of membrane components.

The plasma membrane is made up of phospholipids and proteins. A plasma membrane is different than a cell wall because the plasma membrane allows nutrients and water in, but keeps out harmful toxins and cells from the outside world. The cell wall is mainly composed of carbohydrates, proteins, and lipids. Cells need to break down these materials.

The plasma membrane of a cell is a network of lipids and proteins that forms the boundary between a cell’s contents and the outside of the cell. It is also simply called the cell membrane. The main function of the plasma membrane is to protect the cell from its surrounding environment. It is semi-permeable and regulates the materials that.

The plasma membrane is a flexible, lipid bilayer that surrounds and contains the cytoplasm of the cell. Based on their arrangement of molecules and the presence of certain specialized components, it is also described as the fluid mosaic model.
