Final answer:
Monomers are small molecules that form polymers, which are much larger structures. Proteins, polymers of amino acids, demonstrate the significance of biological macromolecules built from monomers.
Explanation:
Monomers are small molecules that can be assembled into giant molecules referred to as polymers, which are much larger than the molecules we discussed earlier. When lots of similar monomers are joined together by covalent bonds, they form a polymer. For example, one significance of biological macromolecules being built out of monomers is that proteins, which are polymers of amino acids, play crucial roles in almost all biological processes.
