Polymers are made of individual subunit called monomer.

Explanation:

Polymers are lengthy chains built up of replicating molecular subunits, named monomers. The term polymer becomes from poly- (many) and -mer (part). A polymer may be a real or manufactured macromolecule composed of recurring units of a smaller molecule (monomers). The term monomer comes from mono- (one) and -mer (part).

Monomers make polymers by creating chemical bonds or confining supramolecular by a method called polymerization. Examples of polymers comprise plastics like polyethylene, silicones. Polymerization is the method of covalently bonding the smaller monomers into the polymer. While polymerization, chemical groups are failed from the monomers so that they may join together.

Polymers are made of individual sub-unit called "Monomers".

Explanation:

A relatively giant molecule consisting of a chain or network of many chemically bonded monomers identical or similar to each other are termed as together "Polymer". The covalent bond linkage take place between such relatively small molecules named as monomers and showcase a polymer.

This can be understood more easily from daily life example of monomers and polymers which is sugar, used for taste addition in tea or coffee. Regular table sugar is disaccharide sucrose ( which is a polymer), consists of fructose and glucose monosaccharides (which are monomers).
