Fungi and some ptotozoa also have cell walls. They are not the same as the plant cell walls made of cellulose. The other walls might be made from proteins or a substance called chitin. Chitin is another structural carbohydrate. They all serve the same purpose of protecting and maintaining structure, but they are very different molecules.
The cell walls of most fungi are of chitin compounds instead of cellulose; a group fungi known as cryptomycota lack chitinous cell walls. In many ways fungi are more closely related to animals than to plants, and they have been thought to share a common protist ancestor with animals.he cell walls of most fungi are of chitin compounds instead of cellulose; a group fungi known as cryptomycota lack chitinous cell walls.
