A polymer are large molecules made up of repeating units, referred to as monomers.

Explanation:

Polymers are macromolecule with large size and high molecular mass. They consists of several repeating units of simpler molecules known as monomers.

Examples of polymers found in plants are

- starch composed of several glucose units linked by glycosidic bonds

- cellulose composed of several repeating glucose units linked by glycosidic bonds as well

An example of polymers found in animals is

- glycogen composed of several units of glucose monomers linked by glycosidic bonds

Polymers

Explanation:

Polymers are compounds comprising of Long chain of monomer units produced naturally or artificially .

Polymers are very important in everyday life. Polymers are used in producing automobile parts, healthcare machines, nylons, plastics etc.

Polymers also make up some components of living organisms such as starch , cellulose which are found in plants and are excellent sources of energy.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
