Pericycle of dicot root does not take part in the formation of

Options

A. cambium
B. lateral roots
C. root hairs
D. cork cambium

Answer

To solve the question "Pericycle of dicot root does not take part in the formation of," we will analyze the role of pericycle in the root structure and its functions.

### Step-by-Step Solution:

1. **Understanding Pericycle**:
- The pericycle is a layer of cells located just inside the endodermis in the roots of dicotyledonous plants. It plays a crucial role in supporting the root and protecting its vascular structures.

2. **Functions of Pericycle**:
- The primary functions of the pericycle include:
- Supporting the root.
- Protecting vascular tissues.
- Facilitating root growth.
- Dividing to form new structures.

3. **Analyzing the Options**:
- We need to evaluate each option to see if it is formed by the pericycle:
- **Option 1: Cambium**: The pericycle contributes to the formation of cambium, which is involved in secondary growth.
- **Option 2: Lateral Roots**: The pericycle is responsible for the formation of lateral roots, as it can divide and give rise to these roots.
- **Option 3: Root Hairs**: Root hairs are not formed from the pericycle. Instead, they are extensions of the epidermal cells of the root.
- **Option 4: Cork Cambium**: The cork cambium is also formed from the pericycle during secondary growth.

4. **Conclusion**:
- Based on the analysis, the pericycle does not participate in the formation of root hairs. Therefore, the correct answer is **root hairs**.

### Final Answer:
The pericycle of dicot root does not take part in the formation of **root hairs**.
