Which polysaccharide makes up the structure of plant cell walls?
A
fructose
B
starch
C
cellulose
D
glucose
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: -The plant cell wall is a dynamic network of several biopolymers and structural proteins including cellulose, pectin, hemicellulose and lignin. Cellulose is one of the main load bearing components of this complex, heterogeneous structure, and in this way, is an important regulator of cell wall growth and mechanics.

Detailed explanation-3: -Cellulose, as the major component of plant biomass, is the most abundant polysaccharide in the world. Cellulose is a linear polymer consisting of -1, 4-linked D-glucose residues. These glucose chains are tightly bonded by hydrogen bonds to form insoluble fibrous materials.

Detailed explanation-4: -cellulose, a complex carbohydrate, or polysaccharide, consisting of 3, 000 or more glucose units.

Detailed explanation-5: -Hint: Cellulose is the main component which is present in the cell wall of plants. It makes the cell wall rigid whereas starch is used as a food reserve in the plant. Starch is the bond of many glucose molecules joined together.
