Feb 2, 2023 · What is a Cell Membrane. 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.
The cell membrane provides a barrier around the cell, separating its internal components from the extracellular environment. It is composed of a phospholipid bilayer, with hydrophobic internal lipid “tails” and hydrophilic external phosphate “heads.”

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).
Jul 18, 2023 · Cell membranes are an essential component of the cell, providing separation between the intracellular and extracellular environment. They are composed of lipids, proteins and carbohydrates.
The cell membrane is an important structural element of the building block of life - the cell. Its main role is to define what’s inside - the intracellular space - and what’s outside - the extracellular space. It also regulates what comes in or out of the cell - that’s called selective permeability. The cell membrane is basically made up ...
