Fungi—cell wall contains cellulose and chitinBacteria—cell walls have peptidoglycans
Difference in the cell walls of fungi and bacteria
This statement is not entirely accurate. While fungi do have cell walls that contain chitin, they do not have cell walls that contain cellulose. Instead, cellulose is a component of the cell walls in plants and some protists.
Similarly, while bacteria do have cell walls that contain peptidoglycans, not all bacteria have the same type of cell wall. Some bacteria, such as Mycoplasma species, lack peptidoglycan in their cell walls entirely and instead have a cell membrane that is stabilized by sterols. Other bacteria have different types of cell wall materials, such as Gram-negative bacteria which have an outer membrane in addition to a peptidoglycan layer.
So, in summary:
– Fungi have cell walls that contain chitin, but not cellulose.
– Bacteria have cell walls that typically contain peptidoglycans, but there are exceptions.
