Cell Membrane Definition And Function

The plasma membrane protects the cell from damage caused by environmental exposure.

Cell membrane definition and function. A cell membrane functions as an enclosure for the internal organelles and protects them. Cell membrane is made by two layers of lipid films oil molecules with many kinds of membrane proteins. It protects the integrity of the cell along with supporting the cell and helping to maintain the cells shape.

Cell Membrane is the second layer in plant cell present below the cell wall while in animal cell it is the first layer. The cell membrane gives the cell its structure and regulates the materials that enter and leave the cell. It controls the movement of substances in and out of the cells.

The cell membrane supports and protects the cell. Unlike Plasma Membrane other organelles do not perform such functions. The plasma membrane comprises lipids and proteins.

A cell membranes phospholipids and proteins arranged in a bilayer give it semi-permeability allowing some. The cell membrane also called the plasma membrane is found in all cells and separates the interior of the cell from the outside environment. The cell membrane is the outermost limit of the cell but it is more than a simple envelope surrounding the cellular contents.

Cell membrane is a biological membrane that separates the interior of the cell from the outside space and protects the cell from its environment. A cell membrane is a border that covers every cell in a living organism. It is also simply called the cell membrane.

It separates the cell from the external environment. The main function of the plasma membrane is to protect the cell from its surrounding environment. It is also known as the cell surface membrane or plasmalemma.
