Answer the following questions :
What is meant by a polymer?

Explanation

### Step-by-Step Text Solution:

1. **Definition of Polymer**: A polymer is a large molecule that is formed by the chemical combination of many smaller units known as monomers.

2. **Monomers**: Monomers are the basic building blocks of polymers. They are small, simple molecules that can join together in long chains to form a polymer.

3. **Process of Polymerization**: The process through which monomers combine to form a polymer is called polymerization. During this process, the chemical bonds between the monomers are formed, resulting in a larger, more complex structure.
