Polymers are large organic molecules made up of monomers.

Here's a breakdown:

* Monomers: These are small, repeating units that are the building blocks of polymers.

* Polymers: These are long chains formed by the joining of many monomers.

Think of it like a necklace:

* Beads: These represent the monomers.

* Necklace: This represents the polymer, formed by linking the beads together.

Here are some examples of common polymers and their monomers:

* Polyethylene: Monomer: Ethylene

* Polypropylene: Monomer: Propylene

* Nylon: Monomers: Adipic acid and hexamethylenediamine

* DNA: Monomers: Nucleotides
