Fungal cells are similar to plant cells in at ey also have a rigid cell wall. However, e cell wall is made up of chitin and not cellulose. Cell Wall - What's it for? Cell membranes surround every cell you will study. Cell walls made of cellulose are only found around plant cells and a few o er organisms. Cellulose is a specialized sugar at is classified as a structural carbohydrate and not used for energy. If a plant cell is like a water balloon, e cell wall is like a cardboard box at protects e balloon. PROBING WALL STRUCTURE. T he structure of plant cell walls has been investigated by a variety of techniques.
