The correct Answer is:
To solve the assertion and reason question, we will analyze both statements step by step. ### Step 1: Understand the Assertion The assertion states: "Protostele is the simplest stele." - **Explanation**: A stele is the central part of a root or stem, primarily composed of vascular tissue (xylem and phloem). Protostele is indeed considered the simplest form of stele. In protostele, the xylem is solid and surrounded by phloem, with no gaps in between. This structure is primitive and is exemplified by plants such as Selaginella. ### Step 2: Understand the Reason The reason states: "Dictyostele is the most advanced type of stele." - **Explanation**: Dictyostele is characterized by having a central pith with vascular tissues arranged in separate strands or bands. While dictyostele is more complex than protostele, it is not the most advanced type of stele. The most advanced type of stele is found in dicots, known as "eustele," which features a more sophisticated arrangement of vascular tissues. ### Step 3: Evaluate the Truth of Each Statement - The assertion is **true** because protostele is indeed the simplest type of stele. - The reason is **false** because dictyostele is not the most advanced type of stele; eustele holds that distinction. ### Step 4: Conclusion Since the assertion is true and the reason is false, the correct answer to the question is that the assertion is true, but the reason is incorrect. ### Final Answer The correct answer is: Assertion is true, but the reason is false. ---
