What is Plasma membrane? What are the functions of it?
Plasma Membrane 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 becau
