Large molecules made up of small repeating units are called polymers.

Here's a breakdown:

* Monomers: The small, repeating units that make up polymers.

* Polymers: The large molecules formed by the bonding of many monomers.

Here are some examples of polymers:

* Proteins: Made up of amino acid monomers.

* Carbohydrates: Made up of sugar monomers (like glucose).

* DNA and RNA: Made up of nucleotide monomers.

* Plastics: Made up of various monomers depending on the type of plastic.
