The type of polysaccharide which serves as a strengthening tissue in the cell wall of plants is
A
cellulose
B
glucose
C
lactose
D
fructose
Explanation: 

Detailed explanation-1: -Hemicelluloses are highly branched polysaccharides that are hydrogen-bonded to the surface of cellulose microfibrils. This crosslinks the cellulose microfibrils into a network of tough, fibrous molecules, which is responsible for the mechanical strength of plant cell walls.

Detailed explanation-2: -Cellulose is the most important structural polysaccharide present in plants. It is made up of unbranched chains of glucose molecules linked via beta 1-4 glycosidic bonds.

Detailed explanation-3: -Cellulose, a tough, fibrous, and water-insoluble polysaccharide, plays an integral role in keeping the structure of plant cell walls stable. Cellulose chains are arranged in microfibrils or bundles of polysaccharide that are arranged in fibrils (bundles of microfibrils), which in turn make up the plant cell wall.

Detailed explanation-4: -The structural polysaccharide found in plant cell walls is cellulose while the storage polysaccharide found in seeds is starch.

Detailed explanation-5: -Cellulose is the primary structural component responsible for much of the mechanical strength of the cell wall. The distribution and orientation of cellulose microfibrils within the cell wall contribute to the control of cell growth.
