In plants, both cellulose and hemicellulose are major components of which one of the following

Options

A. Plasma membrane
B. Cell wall
C. Nuclear membrane
D. Mitochondria membrane

Answer

To solve the question "In plants, both cellulose and hemicellulose are major components of which one of the following?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components**: Recognize that the question mentions two specific components: cellulose and hemicellulose.

2. **Understand Their Functions**: Cellulose is a polysaccharide that provides structural support in plant cells, while hemicellulose is a complex carbohydrate that also contributes to the structure of the cell wall.

3. **Analyze the Options**: The options given are:
- Plasma membrane
- Cell wall
- Nuclear membrane
- Mitochondria membrane

4. **Evaluate Each Option**:
- **Plasma membrane**: This is primarily made of a phospholipid bilayer and does not contain cellulose or hemicellulose.
- **Cell wall**: This is known to be composed of cellulose as its primary component, along with hemicellulose, pectin, and lignin.
- **Nuclear membrane**: This is also made of lipid bilayers and does not contain cellulose or hemicellulose.
- **Mitochondria membrane**: Similar to the plasma membrane, it is composed of lipid bilayers and does not include cellulose or hemicellulose.

5. **Conclusion**: Based on the analysis, the correct answer is that both cellulose and hemicellulose are major components of the **cell wall**.

### Final Answer:
The correct option is **cell wall**.
