Antibiotics: Antibiotics are drugs used to cure diseases caused by bacteria. There are different kinds of antibiotics which attack different processes and structures in bacteria to kill them or to stop their growth. Bacteria, as you know, are single-celled organisms. One type of antibiotic stops the production of a compound needed for the growth of the cell wall. This prevents the cell wall from expanding when the other parts of the cell are growing. As a result, the cell bursts, which kills the bacteria. Penicillin, an important antibiotic, works in this way.
