In which of the following , cellulose content is maximum?

Options

A. Cotton fibres
B. Wood
C. Rayon
D. Silk

Answer

To determine which option has the maximum cellulose content, we can analyze each option based on what we know about cellulose in various materials:

1. **Understanding Cellulose**:
- Cellulose is a polysaccharide made up of glucose units and is a primary structural component of plant cell walls.

2. **Analyzing the Options**:
- **Cotton Fibers**: Cotton is known for its high cellulose content. Approximately 90% of cotton fiber is cellulose.
- **Wood**: Wood contains cellulose, but its content typically ranges from 40% to 50%.
- **Rayon**: Rayon is a regenerated form of cellulose, but it is not pure cellulose; it is derived from cellulose but undergoes processing.
- **Silk**: Silk is primarily made up of proteins (fibroin and sericin) and contains very little to no cellulose.

3. **Comparing the Cellulose Content**:
- Cotton fibers: ~90% cellulose
- Wood: 40-50% cellulose
- Rayon: Regenerated cellulose, but not as high as cotton
- Silk: Primarily protein, negligible cellulose

4. **Conclusion**:
- Among the options provided, cotton fibers have the highest cellulose content, making it the correct answer.

Thus, the answer to the question "In which of the following, cellulose content is maximum?" is **Cotton Fibers (Option A)**.
