The correct Answer is:
To solve the question regarding the amount of secondary xylem being more on the outer side of the secondary phloem, we can break it down step by step: ### Step-by-Step Solution: 1. **Understanding the Structure**: In dicot plants, there is a structure called vascular cambium, which is responsible for secondary growth. This cambium is located between the xylem (inner) and phloem (outer). 2. **Function of Vascular Cambium**: The vascular cambium produces secondary xylem towards the inner side and secondary phloem towards the outer side. 3. **Activity of Cambium**: The activity of the cambium varies with seasons, but it is generally more active in producing secondary xylem than secondary phloem. 4. **Conclusion on Xylem and Phloem Distribution**: Since the cambium is more active on the inner side, it produces more secondary xylem compared to the amount of secondary phloem produced on the outer side. 5. **Choosing the Correct Option**: Based on the above understanding, the correct answer to the question is (b) "cambium is more active on inner side". ### Final Answer: (b) cambium is more active on inner side. ---
