Detailed explanation-1: -Cellulose and chitin are examples of structural polysaccharides. Cellulose is used in the cell walls of plants and other organisms and is said to be the most abundant organic molecule on Earth.

Detailed explanation-2: -Cellulose is a carbohydrate found in the cell wall of plants. The carbohydrate is a polysaccharide structure. Polysaccharide is made up of a long chain of several sugar units bonded together by chemical linkage.

Detailed explanation-3: -5.3. Cellulose, as is starch, is a carbohydrate. It is a structural polysaccharide, while starch is one of the storage polysaccharides. In terms of quantity, cellulose is the most represented polymer on Earth and is the main support for trees and other plants (cotton, flax, jute, sugarcane, cereals, etc.).

Detailed explanation-4: -Chitin is a large, structural polysaccharide made from chains of modified glucose. Chitin is found in the exoskeletons of insects, the cell walls of fungi, and certain hard structures in invertebrates and fish. In terms of abundance, chitin is second to only cellulose.

Detailed explanation-5: -Cellulose and chitin are both fiber-forming polymers, and as fibers they serve as the load-bearing components of major groups of natural composite tissues-cellulose in many plant-cell walls and chitin in the skeletal materials of many lower animals.
