Which Of These Has A Cell Wall Composed Of Cellulose. This contrasts with the cellwalls of fungi, which are made of chitin, and of bacteria, which are made of peptidoglycan. The cell wall found only in plant cells contain a substance known as cellulose.
A cell wall composed of cellulose and hemicelluloses, pectin and in many cases lignin, is secreted by the protoplast on the outside of the cellmembrane.
Cell walls made of cellulose are only found around plant cells and a few. Cell wall is another such organelle that has a very specific set of functions to perform. The materials in a cell wall vary between species, and in plants and fungi also in plants, the strongest component of the complex cell wall is a carbohydrate called cellulose, which is a polymer of glucose. This tutorial introduces cell walls.
