Middle lamella represents

Options

A. Common wall between adjacent cells
B. Common membrane covering of two adjacent cells
C. Pore between adjacent cells
D. Cementing material between two adjacent cells

Answer

**Step-by-Step Solution:**

1. **Understanding the Middle Lamella**: The middle lamella is a layer found in plant cells that serves as a boundary between adjacent cells. It is primarily made up of pectins, which are polysaccharides.

2. **Function of the Middle Lamella**: The main function of the middle lamella is to act as a cementing material that holds together the cell walls of adjacent plant cells. This ensures structural integrity and communication between cells.

3. **Formation of the Middle Lamella**: The middle lamella is formed during cell division when a cell plate is created. This cell plate eventually develops into the middle lamella, which is the first layer that forms between two newly divided cells.

4. **Identifying the Correct Option**: Given the options:
- A common wall between adjacent cells
- A common membrane covering of two adjacent cells
- Pore between adjacent cells
- Cementing material between two adjacent cells

The correct answer is "cementing material between two adjacent cells" because the middle lamella specifically serves this purpose.

5. **Conclusion**: Therefore, the middle lamella represents the cementing material between two adjacent cells.
