True or False Question True or false: Bacteria are the only organisms that have cell walls composed of peptidoglycan. True False Need help? Review these concept resources.

True! Peptidoglycan is a unique polymer that makes up the cell walls of bacteria, providing structural support and shape. This remarkable molecule is exclusive to prokaryotes, which means other organisms like plants and fungi have entirely different cell wall compositions, using cellulose and chitin, respectively. If you think about it, peptidoglycan is like a bacterial fortress, helping them withstand various environmental pressures. It's also a key target for antibiotics, as they aim to disrupt cell wall synthesis, leading to the bacteria's downfall. Just another reason to appreciate the quirky world of microbes!
