_ is most abundant carbohydrate in nature.
Correct answer: D. Cellulose
- A. Waxes
- B. Glycerol
- C. Starch
- D. Cellulose
Explanation
Cellulose is the most abundant carbohydrate in nature due to its role as a structural component in the cell walls of plants. It is a polymer made of glucose molecules linked together in a specific configuration, giving plants their rigidity and form. The vast quantity of plant biomass on Earth makes cellulose the most prevalent carbohydrate. Other options, such as waxes and glycerol, are not carbohydrates, and starch, though abundant, primarily acts as an energy storage molecule rather than a structural component.
