- Membrane | Definition, Structure, Functions | Britannica
membrane, in biology, the thin layer that forms the outer boundary of a living cell or of an internal cell compartment The outer boundary is the plasma membrane, and the compartments enclosed by internal membranes are called organelles
- Cell membrane - Wikipedia
The apical membrane or luminal membrane of a polarized cell is the surface of the plasma membrane that faces inward to the lumen This is particularly evident in epithelial and endothelial cells, but also describes other polarized cells, such as neurons
- Cell Membrane: Definition, Structure, Functions with Diagram
The cell membrane, also called the plasma membrane, is a thin layer that surrounds the cytoplasm of all prokaryotic and eukaryotic cells, including plant and animal cells
- Plasma Membrane (Cell Membrane)
The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment In bacterial and plant cells, a cell wall is attached to the plasma membrane on its outside surface

Figure 3 1 2- Cell Membrane: The cell membrane of the cell is a phospholipid bilayer containing many different molecular components, including proteins and cholesterol, some with carbohydrate groups attached
- Cell Membrane - The Definitive Guide | Biology Dictionary
The cell membrane, also known as the plasma membrane, is a double layer of lipids and proteins that surrounds a cell It separates the cytoplasm (the contents of the cell) from the external environment
- Cell Membranes | Learn Science at Scitable - Nature
Scientists who model membrane structure and dynamics describe the membrane as a fluid mosaic in which transmembrane proteins can move laterally in the lipid bilayer
- What Is a Biological Membrane? Definition and Functions
A biological membrane controls which substances can enter and exit the cell or organelle, protecting the internal environment This selective nature is determined by the hydrophobic core of the lipid bilayer, which repels large, water-soluble molecules and charged ions
