Beside cellulose microfibrils, the other two cell with networks are

Options

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

Answer

To answer the question, "Besides cellulose microfibrils, the other two cell wall networks are," we need to identify the components of the plant cell wall along with cellulose microfibrils.

### 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 structure and function.

2. **Identifying Other Components**: Besides cellulose, two significant components of the plant cell wall are:
- **Pectin**: This is a polysaccharide that plays a crucial role in cell wall structure, helping in cell adhesion and wall extension during growth.
- **Glycoproteins**: These are proteins that have carbohydrate groups attached to them. They are involved in various functions, including cell signaling and structural integrity.

3. **Analyzing the Options**:
- Option A: Pectin and Hemicellulose
- Option B: Hemicellulose and Protein
- Option C: Pectin and Glycoprotein
- Option D: Pectin and Hemicellulose

4. **Selecting the Correct Answer**: Based on our understanding, the correct answer is Option C: Pectin and Glycoprotein. These two components, along with cellulose microfibrils, form the essential networks in the plant cell wall.

### Final Answer:
The other two cell wall networks, besides cellulose microfibrils, are **Pectin and Glycoprotein** (Option C).
