Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The cell wall in plants contains which carbohydrate?
A
Carbon
B
glucose
C
fructose
D
cellulose
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: -Plant cells are surrounded by cell walls built largely from complex carbohydrates. The primary walls of growing plant cells consist of interdependent networks of three polysaccharide classes: cellulose, cross-linking glycans (also known as hemicelluloses), and pectins.

Detailed explanation-3: -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. Polysaccharides examples are chitin, glycogen, cellulose, and starch.

Detailed explanation-4: -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-5: -Complex carbohydrates, or polysaccharides, consist of hundreds or even thousands of monosaccharides. They include starch, glycogen, cellulose, and chitin.
