What is a plasma membrane?

Answer 1

A plasm membrane is a permeable memrane located within the cell wall. It serves many functions for the cell, including energy generation and transport of chemicals.

Answer 2

The plasma membrane, is the thin, outermost membrane that separates each cell from its outside environment. The membrane lets internal metabolic reactions proceed in controllable ways, but does not isolate the cell interior. Water and gases cross in and out freely, but the flow of other substances across the membrane is controlled. Membranous protective covering of the cell. -- The plasma membrane is the membrane surrounding a cell that separates the cell from its external environment - responsible for barrier function; consists of a phospholipid bilayer (polar head group, nonpolar tails) and associated membrane lipids and proteins (integral-help transport hydrophilic molecules across bilayer, peripheral, and lipid-anchored proteins).

Answer 3

the plasma membrane is a semi permeable membrane which permits the flow of materials from the cell to its outer surroundings and also from the cells outer surroundings into the cell .it also does not permit the entry some materials to go in an out of the cell.it permits the the flow of water into the cell and out of it according to the cells neccessity .it also permits the entry of oxygen and CO2 according to the cells necessity.

Answer 4

Plasma membrane defines the boundary of the cell and regulates the flow of material into and out of the cell.If it ruptures in case then generally it heals within no time but if rupturing does not heal, the cell contents will spill over and cell is killed.

Answer 5

It is the outer membrane of the cell comprised of a bilayer of phopholipids, cholesterol and membrane proteins.

Answer 6

The cell plasma membrane protects the cell and regulates what substances enter or leave the cell.
