Chitin is a fibrous substance while cellulose is an insoluble substance Chitin is a major component of the exoskeleton of arthropods and fungi cell wall whereas cellulose is a major component of plant cell wall The monomer
Monomer
A monomer (mono-, "one" + -mer, "part") is a molecule that may bind chemically or supramolecularly to other molecules to form a (supramolecular) polymer. The process by which monomers combine end to end to form a polymer is called polymerization. Molecules made of a small number of monomer units (up to a few dozen) are called oligomers.

What is the difference between starch glycogen and cellulose?
Starch, glycogen, and cellulose all are forms of glucose stored inside the living cells. The hydroxyl groups in all three polysaccharides are held together by hydrogen bonds with adjacent chains. All three of these polysaccharides have 1-4 glycosidic bonds in monomers. The starch vs. cellulose vs. glycogen differences are listed here:
What is the difference between cellulose and chitin?

Chitin is a high molecular weight polymer, specifically β (1-4) (N-acetyl-d-glucoamine), as shown in Fig. What is the difference between starch cellulose and chitin?
What type of glycosidic bonds are in cellulose?
The glucose units in cellulose are linked by β glycosidic bonds, different than the α glycosidic bonds found in glycogen and starch. Cellulose has more hydrogen bonds between adjacent glucose units, both within a chain and between adjacent chains, making it a tougher fiber than glycogen or starch.
Does starch have glucose residues?
Starch contains glucose residues as α (1-4) glycosidic bonds in amylose, while in amylopectin α (1-6) glycosidic linkages at branching points, otherwise α (1-4) linkages. Glycogen also contains α (1-4) and α (1-6) (at branching points) glycosidic bonds between their monomers. The molar mass of starch varies.
