What is the function of a cell membranes?

Answer 1

The cell membrane controls exchange of materials such as nutrients and waste between cells and their environment. They have other important functions, for example to enable cells to receive hormones.
Cell membrane is not a function of the brain. This is not found in plants.

Answer 2

The function of the cell membrane is to control what enters and leaves the cell.

Answer 3

Control movement of materials in / out of cell .

Answer 4

Control movement of materials in / out of cell .

Answer 5

The basic function of the cell membrane is to protect the cell from its surroundings.

Answer 6

Cell membrane

The cell membrane is a biological membrane that separates the interior of all cells from the outside environment which protects the cell from its environment. The cell membrane consists of a lipid bilayer, including cholesterols that sit between phospholipids to maintain their fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that go across the membrane serving as membrane transporters, and peripheral proteins that loosely attach to the outer side of the cell membrane, acting as enzymes shaping the cell. 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. In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signaling 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
