Answer:
Cell identification-Glycoproteins
Receptors, transporters-Membrane proteins
Hydrophobic interior of membrane-Fatty acid tails
Maintains rigidity-Cholesterol
Hydrophilic surfaces of membrane-Phosphate heads
The the above matches indicated the phospholipid bi- layer of cells.This set up ensures that the cells control the movements of substances across its walls or membranes.
The structure also ensures fluidity of the cells which ensures insulation during cold weather. it also prevents the cell from being too rigid under certain condition.
