The layer of thin walled cells which separates the wood from phloem in dicot plants is called

Options

A. Endodermis
B. Pericycle
C. Vascular cambium
D. Cork cambium

Answer

To answer the question, "The layer of thin-walled cells which separates the wood from phloem in dicot plants is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Plant Tissues**:
- In dicot plants, the vascular system consists of two main types of tissues: xylem (wood) and phloem. Xylem is responsible for water and nutrient transport, while phloem transports food.

2. **Identifying the Layers**:
- Between the xylem and phloem, there exists a layer of cells that plays a crucial role in secondary growth.

3. **Defining Vascular Cambium**:
- The vascular cambium is a layer of thin-walled cells located between the xylem and phloem. It is responsible for the production of secondary xylem (wood) towards the inner side and secondary phloem towards the outer side during secondary growth.

4. **Eliminating Incorrect Options**:
- Endodermis: This is found in the root cortex and does not separate wood from phloem.
- Pericycle: This is located inside the endodermis and does not separate wood from phloem.
- Cork Cambium: This is involved in the formation of bark and is not the layer separating xylem and phloem.

5. **Conclusion**:
- Therefore, the correct answer to the question is **vascular cambium**, as it is the layer of thin-walled cells that separates the wood (xylem) from the phloem in dicot plants.

### Final Answer:
The layer of thin-walled cells which separates the wood from phloem in dicot plants is called **vascular cambium**.
