Detailed explanation-1: -Polymer molecules, or macromolecules, are composed of large numbers of linked, small repeat units . The units from which polymers are synthesized are called monomers. Polymers may be made from one kind of monomer, giving homopolymers, or from several kinds of monomers, giving copolymers.

Detailed explanation-2: -A polymer is made up of a number of joined-together monomers. One way of thinking about polymers is like a chain of connected-up paperclips. A polymer is a large molecule made up of smaller, joined-together molecules called monomers.

Detailed explanation-3: -Polymers are not restricted to monomers of the same chemical composition or molecular weight and structure. Some natural polymers are composed of one kind of monomer. Most natural and synthetic polymers, however, are made up of two or more different types of monomers; such polymers are known as copolymers.

Detailed explanation-4: -Biomacromolecules are large biological polymers, such as nucleic acids, proteins, and carbohydrates, that are made up of monomers linked together.

Detailed explanation-5: -Polymers are very large molecules compared to water. They have many more atoms than a water molecule–from 10, 000 to 100, 000 atoms per molecule. The word polymer is derived from the Greek root poly-, meaning many, and mer, meaning part or segment.
