STRUCTURE AND FUNCTION OF CELL MEMBRANES12. Cell or Plasma Membrane Outer membrane of cells that controls movement of substances in and out of the cell Double layer bi-layer In plants and bacteria this is within the cell wall. The cell membrane is a complex barrier separating every cell from its external environment.

1 Isolate cells contents from outside environment 2 Regulate exchange of substances between inside and outside of cell 3 Communicate with other cells. MAIN IDEAS KEY POINT EXPLANATION NOTES a Show the detailed structures of typical plant and animal cells and state the organelles present. It is a double-layered membrane composed of proteins and lipids.

Phospholipid molecules form a bilayer - phospholipids are fluid and move laterally Peripheral proteins are bound to either the inner or outer surface of the membrane Integral proteins - permeate the surface of the membrane. Cell wall In bacteria and plant cells the outermost cell cover present outside the plasma membrane is the cell wall about which we shall study now. Semirigid structure that lies outside the cell membrane in almost all bacteria.
