cell walls
Rigid cellular boundaries
Cell walls are the rigid outer layers that surround certain cells, providing structural support and protection.
Plant cells have cell walls made of cellulose; bacterial cell walls contain different compounds.
Unlike cell membranes, which all cells have, cell walls are found only in plants, fungi, bacteria, and some other organisms.
The antibiotic targets bacterial cell walls.
