These kind of mutations in the bacterial genome will lead to the phenomenon of bacterial resistance. As described, the peptidoglycans continues to be cross linked as usual but the over all new resulting cell wall has developed a resistance against the antibiotic penicillin due to non recognition enhancement by the bacterial resistance genes.
Answer: Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.
