The correct Answer is:
To solve the question regarding the correctness of the statements about cambium and its functions in the young dicot stem, we will analyze each statement step-by-step. ### Step-by-Step Solution: 1. **Analyzing Statement (a)**: - The statement claims that in the young dicot stem, cambium is present in patches as a single layer between xylem and phloem. - **Explanation**: In young dicot stems, the cambium is indeed found in patches, known as intrafascicular cambium, situated between the xylem and phloem. This layer is crucial for secondary growth. - **Conclusion**: This statement is **correct**. 2. **Analyzing Statement (b)**: - The statement asserts that vascular cambium and cork cambium both form the lateral meristem. - **Explanation**: Both vascular cambium (which produces xylem and phloem) and cork cambium (also known as phellogen, which produces cork) are types of lateral meristems responsible for the increase in girth or thickness of the plant. - **Conclusion**: This statement is **correct**. 3. **Analyzing Statement (c)**: - The statement claims that medullary cells are derived from the interfascicular cambium. - **Explanation**: The interfascicular cambium is formed from the intrafascicular cambium as the plant matures. It contributes to the formation of medullary rays, which consist of medullary cells. - **Conclusion**: This statement is **correct**. ### Final Conclusion: Since all three statements (a), (b), and (c) are correct, the answer to the question is that all statements are true. Thus, the correct option is **D**, which states that all three statements are correct. ---
