Cotton is a pure form of:
Correct answer: C. Cellulose
- A. Starch
- B. Amylopectin
- C. Cellulose
- D. Pectins
Explanation
Cotton is a pure form of cellulose, which is a polysaccharide that serves as the main structural component of plant cell walls. This makes cellulose the primary substance in cotton fibers. The other options-starch, amylopectin, and pectins-are different types of carbohydrates with distinct roles in plants. Starch, including amylopectin, is primarily used for energy storage, while pectins are involved in maintaining the structure of fruit and plant cells, not in forming fibers like cellulose does.

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.
