Assertion :- Pericycle of monocot roots show dual functioning.
Reason:- Pericycle of monocot root helps in formation of lateral roots and secondary growth.

Options

A. If both Assertion & Reason are True & Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but the Reason is a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are false.

Answer

### Step-by-Step Text Solution:

1. **Understanding the Assertion**: The assertion states that the pericycle of monocot roots shows dual functioning. To evaluate this, we need to understand what the pericycle is and its roles in monocot roots.

2. **Understanding the Reason**: The reason given is that the pericycle of monocot roots helps in the formation of lateral roots and secondary growth. We need to analyze whether this statement is accurate for monocot roots.

3. **Structure of Monocot Roots**: Monocot roots have a specific structure that includes the epidermis, cortex, endodermis, pericycle, vascular bundles, and pith. It is essential to note that monocot roots do not exhibit secondary growth.

4. **Function of Pericycle**: The pericycle is responsible for the formation of lateral roots in both monocots and dicots. However, in monocots, it does not contribute to secondary growth, which is a characteristic feature of dicot roots.

5. **Conclusion on Assertion and Reason**: Since the pericycle in monocots does not facilitate secondary growth, the assertion that it shows dual functioning is incorrect. Therefore, both the assertion and the reason are false.

6. **Final Answer**: Based on the analysis, the correct option is that both the assertion and the reason are false.
