This polysaccharide is important to the structure of plant cell walls
A
Starch
B
Glycogen
C
Cellulose
D
Chitin
Explanation: 

Detailed explanation-1: -In the cell walls of higher plants, the tensile fibers are made from the polysaccharide cellulose, the most abundant organic macromolecule on Earth, tightly linked into a network by cross-linking glycans.

Detailed explanation-2: -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.

Detailed explanation-3: -Cellulose is a major component of plant cell walls, and is the world’s most abundant biopolymer. Cellulose contains apparently simple linear chains of glucose residues, but these chains aggregate to form immensely strong microfibrils.

Detailed explanation-4: -Plant cell walls are primarily made of cellulose, which is the most abundant macromolecule on Earth. Cellulose fibers are long, linear polymers of hundreds of glucose molecules. These fibers aggregate into bundles of about 40, which are called microfibrils.

Detailed explanation-5: -cellulose, a complex carbohydrate, or polysaccharide, consisting of 3, 000 or more glucose units.
