Solution
The correct option is D Cellulose
Cellulose is a polysaccharide. It is formed by the linkage of beta 1,4 linkage of glucose unit. It is an important component of cell wall of the plant. It is used for production of paper.Pectin is mostly present in the cell wall of the plant and the concentrated in the skin of fruits. It consists of esterified D-galacturonic acid resides in an alpha-(1-4) chain.
Starch is formed by a-1,4 linkages between two glucose unit which is broken down during its digestion.
Lignin is present in the cell wall which provides strength to the plant. It is a complex polymer of aromatic alcohol.So, the correct answer is option D.
