Serve as the selective channels  for the  influx of certain substances into the cells, and the out flux of wastes.This is through ion channels for the movements of ions across.

Provide insulation to the cells,to maintain the constant internal temperature,this is through the presence of lipids as( Phospholipids and cholesterol).The latter prevent the clogging of the lipids in the cell membrane therefore preventing frozen up of the cell membrane,providing insulation.

Separation of metabolic process in the cell.

Explanation:

Cell membrane-This is present in all cells.But the variation of its constituents makes it unique to each cell. Although it performs the same role, the location and role the cells it bounded, reflects its  constituents, it is made up of lipids, carbohydrate, protein and cholesterol
