Very long and large organic molecules are called macromolecules and are made up of smaller units called monomers. Examples of small units include sugars which combine to form carbohydrates , nucleotides, which combine to form nucleic acids; and amino acids which form proteins.

Explanation:

Examples of carbohydrates which are polymers of sugar are cellulose, starch, chitin etc. Nucleic acids namely the DNA and RNA are composed of sugar, nitrogen bases and phosphate group.  Monomers that make up proteins are amino acids.
