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.
1 In the strict sense organisms classified as fungi have cell walls composed primarily of chitin. 2  However, we will be also be covering fungi that do not have chitin in their cell walls. 3  Fungi have a common nutritional mode: Absorption: The transport of food from their substrate into their cell walls. The assimilative stage of the fungal body, i.e. mycelium or yeast, has a cell wall. 2  In the strict sense organisms classified as fungi have cell walls composed primarily of chitin. 3  However, we will be also be covering fungi that do not have chitin in their cell walls.
