Plasma membrane is a biological membrane that separates the interior of all cells from the outside environment. The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells.

Contain, protect and provide unit structure. The plasma membrane is classified as an organelle of the cell.

The plasma membrane is an outer boundary and functional "traffic-cop" of every biological cell. Just like the outer layers of multicellular organisms, its primary function is to contain, protect and provide unit structure. The plasma membrane is classified as an organelle of the cell.

The plasma membrane is selectively permeable in that it helps control what moves into and out of its cell (thus the "traffic-cop" label). It consists of a thin structured bilayer of phospholipids and protein molecules; it is found as a component of every biological cell, and serves to divide the inner environment of the cell from the outer environment (much like the skin of animals). The surfaces of plasma membranes are generally studded with proteins that perform different functions, like the reception of nutrients or the anchoring of the flagellum. The plasma membrane is normally about ten nanometers thick.

The structure of the plasma membrane is often referred to as a fluid mosaic because it is a ...more

Its main functions are to separates the content of a cell from external environment, regulates the movement of substances entering and leaving the cell and allows the exchange of nutrients between the cell and its environment.

Plasma membrane is semi-permeable and acts as a selective barrier. Its main functions are to separates the content of a cell from external environment, regulates the movement of substances entering and leaving the cell and allows the exchange of nutrients between the cell and its environment.
