Explanation:
Human cell do not contain cell wall. Cell wall is the outer layer present outside the cell membrane in plants, bacteria, and fungi. Cell wall present in plants, bacteria and fungi give extra protection to the cell. Antibiotics helps to stop the bacteria from building a cell wall. Antibiotics contain penicillin which works against bacteria cell to form a cell wall. In bacteria protein synthesis is essential part of cell, there are many antibiotics which stops the process of protein synthesis by cutting the protein chain in bacteria cell to stops it's further growth to make it difficult to sustain.
