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.
