Two cell wall networks, other than cellulose microfibrils are

Options

A. Protein and hemicellulose
B. Hemicellulose and glycoprotein
C. Pectin and glycoprotein
D. Pectin and hemicellulose

Answer

To answer the question regarding the two cell wall networks other than cellulose microfibrils, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Cell Wall Composition**:
- The plant cell wall is primarily composed of cellulose microfibrils, which provide structural support. However, there are other components that contribute to the cell wall's architecture.

2. **Identifying Other Cell Wall Networks**:
- Apart from cellulose, two important networks found in the plant cell wall are:
- **Pectin**: This is a polysaccharide that helps in cell wall stability and flexibility. It allows the primary cell wall to expand during plant growth.
- **Glycoproteins**: These are proteins that have carbohydrate groups attached to them. They play a crucial role in the structural integrity of the cell wall and are involved in cell signaling.

3. **Evaluating the Options**:
- The question provides several options to choose from:
- Option 1: Protein and hemicellulose
- Option 2: Hami cellulose and glycoprotein
- Option 3: Pectin and hemicellulose
- Based on our understanding, the correct networks other than cellulose microfibrils are **Pectin** and **Glycoproteins**.

4. **Conclusion**:
- Therefore, the two cell wall networks other than cellulose microfibrils are **Pectin** and **Glycoproteins**.

### Final Answer:
The two cell wall networks other than cellulose microfibrils are **Pectin** and **Glycoproteins**.
