Dehydradtion reactions cause cells to make polymers from monomers.
Polymerization
http://en.wikipedia.org/wiki/Polymerization
The cells make "polymers" through building blocks of monomers by the process of anabolic synthesis. And breaking them down through catabolism.
The chemical mechanism by which cells make polymers from monomers is called dehydration synthesis. In other words, water is removed to allow two monomers to bond to one another.

Monomers are smaller molecules which, connected by covalent chemical bonds, link together to form huge polymer molecules. These molecules tend to be very strong, and are found in substances such as plastics. Remember: mono=1, poly=many
monomer = amino acidpolymer = polypeptide (= polypeptide chain)A monomer is one unit in a chain of repeating units. Amino acids are assembled in cells into chains called polypeptides.A protein may consist of just one polypeptide, or more than one. For example, human growth hormone has only one chain, but hemoglobin has four.
Nucleic Acids are polymers of nucleotides with very specific functions in cells.
Not all polymers are toxic. Plastic for example is a polymer and is made from a non biodegradable material, however, is not toxic unless consumer. Polymers are known to increase risk of cancer, and even radiation poisoning.
Chemical
Catabolic reactions breakdown polymers into monomers. Enzymes in our body essentially aid in that process. Polymers cannot be absorbed into the cells so it has to be broken down into simpler units.
No, polymers must be broken into monomers, or at least dimers, to be taken into the cells for procession. That is why you have many powerful digestive enzymes.

Since you haven't mentioned the context where the liked units, therefore 1. If you are asking about polymers, then they are called monomers. 2. If you are asking about living organisms they are called cells. 3. if you are asking about solids, they are called unit cells.

The chemistry industry is working on new uses for polymers as well. In development are conductive polymers for printable electronics. Polymer Electrolyte Membrane, PEM, (or Proton Exchange Membrane) fuel cells are already in use in hydrogen fuel cell vehicles. The industry is also working on materials for advanced fuel cells including a polymer electrolyte fuel cell (PFC).

Without chemical reactions, chemical processes could not occur. Without chemical processes, life is not possible. Anything alive is alive (at least in part, if not in sum) because of the biochemical processes going on in the organism. No chemistry equals no life. All living things are, without exception, biochemical mechanisms or biochemical machines.
