Cotton is the pure form of:
Correct answer: A. Cellulose
- A. Cellulose
- B. Glycogen
- C. Wax
- D. Protein
Explanation
Cotton is composed almost entirely of cellulose, a complex carbohydrate that forms the structural component of plant cell walls. Cellulose is a linear polymer of glucose molecules connected by β-1,4 glycosidic bonds, which provides rigidity and strength to the fibers of cotton. Option B, Glycogen, is incorrect because it is a storage polysaccharide found in animals, not plants. Option C, Wax, is incorrect as it refers to lipids that serve as protective coatings rather than structural fibers. Option D, Protein, is incorrect because proteins consist of amino acids and are not the primary structural component of cotton.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
