Differnet layers of cell wall are

Options

A. Middle lamella and primary wall
B. Primary wall and secondary wall
C. Middle lamella, primary wall and secondary wall
D. Wall layers exclude midddle lamella

Answer

### Step-by-Step Solution:

1. **Understanding the Cell Wall**: The cell wall is a rigid outer layer that surrounds the cell membrane in plant cells, providing structural support and protection.

2. **Identifying the Layers**: The cell wall consists of three main layers:
- **Primary Cell Wall**: This is the first layer that is formed during cell division. It is thin, flexible, and allows for cell growth.
- **Secondary Cell Wall**: This layer is formed after the primary wall and is thicker and more rigid. It provides additional support and is often lignified.
- **Middle Lamella**: This is a layer that acts as a cementing substance between the primary walls of adjacent cells. It is rich in pectins.

3. **Listing the Layers**: Based on the understanding, the three layers of the cell wall are:
- Middle Lamella
- Primary Cell Wall
- Secondary Cell Wall

4. **Choosing the Correct Option**: The question asks for the different layers of the cell wall. The correct answer includes all three layers:
- Option C: Middle Lamella, Primary Wall, and Secondary Wall.

5. **Final Answer**: Therefore, the answer to the question is **Option C**.
