Assertion: Both apical meristem and intercalary meristem areprimary meristems.
Reason: Both of these meristems appear early in life of a plant and help in the formation of the primary plant body.

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 Solution:**

1. **Understanding the Assertion:**
- The assertion states that both apical meristem and intercalary meristem are primary meristems.
- **Explanation:** Apical meristem is located at the tips of roots and shoots, while intercalary meristem is found between mature tissues. Both are classified as primary meristems because they are involved in the initial growth of the plant.

2. **Understanding the Reason:**
- The reason provided states that both types of meristems appear early in the life of a plant and contribute to the formation of the primary plant body.
- **Explanation:** Primary meristems, including apical and intercalary, develop from the promeristem during the early stages of plant development, which is crucial for the plant's growth and structure.

3. **Evaluating the Truth of the Assertion:**
- Since both apical and intercalary meristems are derived from the promeristem and are responsible for primary growth, the assertion is true.

4. **Evaluating the Truth of the Reason:**
- The reason correctly explains that these meristems appear early in the plant's life and are essential for forming the primary plant body, making the reason true as well.

5. **Conclusion:**
- Both the assertion and the reason are true, and the reason accurately explains the assertion. Therefore, we conclude that both statements are correct.

**Final Answer:**
Both the assertion and the reason are true, and the reason is the correct explanation of the assertion.
