define cell membrane...??? ​

Answer 1

hey mate your answer plz mark as brainlist

The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment[1][2] consisting of a lipid bilayer with embedded proteins. The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.[3] In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled

thank you for 50 points

Answer 2

HLO BUDDY HERE IS YOUR ANSWER :-.

CEL MEMBRANE :- cell membraneor also known as plasma membrane is a semi permeable membrane of a cell that covering the outer of cytoplasm.

Its is called semi permeabke because its doesnot allows the passing of all meterials it selectively allows the passing of materials, substances.

HOPE ITS HELP YOU.
