Answer:
Polymer, any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, that are multiples of simpler chemical units called monomers. example is protein, a polymer made from amino acids covalently bonded together.
Molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance. example is Oxygen and hydrogen making up water molecule.
