The layer of the cell wall that is formed soon after the cell division and is composed of calcium pectate is

Options

A. middle lamella
B. primary cell wall
C. secondary cell wall
D. cell coat

Answer

To answer the question regarding the layer of the cell wall that is formed soon after cell division and is composed of calcium pectate, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of the Cell Wall**:
- The cell wall is primarily made up of various components, including cellulose, hemicellulose, lignin, and pectins.

2. **Understand the Function of the Middle Lamella**:
- The middle lamella is the layer that forms between the cell walls of adjacent plant cells. It is rich in pectins, which are polysaccharides that help in cell adhesion.

3. **Composition of the Middle Lamella**:
- The middle lamella is specifically composed of calcium pectate and magnesium pectate. This composition is crucial for the stability and integrity of the cell wall.

4. **Differentiate Between Cell Wall Layers**:
- **Primary Cell Wall**: Made mainly of cellulose, it provides structural support.
- **Secondary Cell Wall**: Composed of cellulose, hemicellulose, and lignin, it provides additional strength and rigidity.
- **Cell Membrane (Cell Coat)**: Composed of glycerophospholipids, it does not include calcium pectate.

5. **Conclusion**:
- Given the information, the layer of the cell wall that is formed soon after cell division and is composed of calcium pectate is the **Middle Lamella**.

### Final Answer:
The correct answer is **Middle Lamella**.
