Bacterial Cell Walls

Fungi, bacteria, and plants all possess cell walls, yet their compositions differ significantly: bacteria utilize peptidoglycan, while plants use cellulose and fungi rely on chitin. The distinction between gram positive and gram negative bacteria lies in their structural differences, with gram positive bacteria featuring a thicker cell wall, while gram negative bacteria have a thinner wall sandwiched between two membranes. Understanding these variations is crucial for classifying bacteria and appreciating their motility.
