Cellulose is the polymer of

Options

A. L - fructose
B. D - fructose
C. D - glucose
D. Amylose

Answer

**Step-by-Step Solution:**

1. **Understanding Cellulose**: Cellulose is a type of carbohydrate known as a polysaccharide. It is primarily composed of long chains of glucose units.

2. **Identifying the Monomer**: The monomer (or building block) of cellulose is glucose. Specifically, it is made up of β-D-glucose units linked together.

3. **Linkage Type**: The glucose units in cellulose are connected by β-1,4-glycosidic linkages. This specific type of linkage is crucial for the structural properties of cellulose.

4. **Function of Cellulose**: Cellulose serves as a major structural component of the cell wall in plants. It provides rigidity and strength, which is essential for plant structure.

5. **Eliminating Incorrect Options**:
- Fructose is not the correct answer because cellulose is not made from fructose.
- Amylose is another polysaccharide but is a polymer of α-D-glucose, not β-D-glucose.
- Galactose is also not the correct answer as cellulose is specifically made from glucose.

6. **Conclusion**: Based on the above points, the correct answer to the question "Cellulose is the polymer of" is β-D-glucose.

**Final Answer**: Cellulose is the polymer of β-D-glucose.
