The correct Answer is:
To determine which statements about meristematic tissues are correct, let's analyze each statement one by one. ### Step-by-Step Solution: 1. **Statement I: Apical meristem is found at the root and shoot apices of the plant.** - **Analysis:** The apical meristem is indeed located at the tips (apices) of roots and shoots. It is responsible for the primary growth of the plant, allowing it to grow taller and deeper. - **Conclusion:** This statement is **correct**. 2. **Statement II: Intercalary meristem is a secondary meristematic tissue.** - **Analysis:** Intercalary meristem is found between mature tissues, typically at the nodes of stems and at the base of leaves. It is classified as a primary meristem, not a secondary meristem. Therefore, this statement is incorrect. - **Conclusion:** This statement is **incorrect**. 3. **Statement III: The lateral meristem is found in the matured regions of the root and shoot.** - **Analysis:** Lateral meristems, such as the vascular cambium and cork cambium, are indeed found in the mature regions of roots and shoots. They contribute to secondary growth, which increases the thickness of the plant. - **Conclusion:** This statement is **correct**. 4. **Statement IV: Lateral meristematic tissue contributes to the secondary growth of the plant.** - **Analysis:** Lateral meristems are responsible for secondary growth in plants, which increases the girth of stems and roots. This is a key function of lateral meristems. - **Conclusion:** This statement is **correct**. ### Summary of Conclusions: - **Correct Statements:** I, III, IV - **Incorrect Statement:** II ### Final Answer: The correct statements about meristematic tissues are I, III, and IV. ---
