In which layer of abscission zone, the breakdown of cells occur?
(a) Gonidial layer
(b) Protective layer
(c) Seperation layers
(d) All of these

Options

A. Gonidial layer
B. Protective layer
C. Seperation layers
D. All of these

Answer

To determine which layer of the abscission zone is responsible for the breakdown of cells, we can analyze the provided options step by step.

### Step-by-Step Solution:

1. **Understanding the Abscission Zone**:
- The abscission zone is a specific area in deciduous trees where leaves detach from the stem. It is crucial for the process of leaf fall.

2. **Identifying the Layers of the Abscission Zone**:
- The abscission zone consists of several layers, including the protective layer, the separation layer, and the gonidial layer.

3. **Function of Each Layer**:
- **Gonidial Layer**: This layer is not primarily involved in the breakdown of cells; it plays a different role in the abscission process.
- **Protective Layer**: This layer serves to protect the underlying tissues during the abscission process but does not directly contribute to cell breakdown.
- **Separation Layer**: This is the layer where the breakdown of cells occurs. It has cells with weak walls that are more susceptible to breakdown during the abscission process.

4. **Conclusion**:
- Based on the analysis, the breakdown of cells occurs specifically in the **separation layer**. Therefore, the correct answer is **(c) Separation layer**.

### Final Answer:
(c) Separation layer
