Intercellular matrix or common layer between the primary walls of adjacent cells is

Options

A. Middle lamella
B. primary wall
C. Secondary wall
D. periplasmic space

Answer

To answer the question regarding the intercellular matrix or the common layer between the primary walls of adjacent cells, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Cell Structure**:
- In plant cells, there are various layers that make up the cell wall. The primary wall is the first layer formed during cell growth.

2. **Identifying the Layers**:
- The primary wall is the outermost layer of a plant cell, while the secondary wall, if present, is formed inside the primary wall after the cell has matured.

3. **Defining the Intercellular Matrix**:
- The intercellular matrix refers to the substance that fills the space between adjacent cells. This is crucial for cell communication and structural integrity.

4. **Identifying the Middle Lamella**:
- The specific layer that acts as the intercellular matrix between the primary walls of adjacent plant cells is known as the middle lamella. It is primarily composed of pectins, which help in binding cells together.

5. **Conclusion**:
- Therefore, the correct answer to the question is that the intercellular matrix or the common layer between the primary walls of adjacent cells is called the **middle lamella**.

### Summary of the Answer:
The intercellular matrix or common layer between the primary walls of adjacent cells is known as the **middle lamella**.
