I want to know the answer to the following question:
What results from the development of xylem on the inside and phloem on the outside?
All the background I'm provided with is that "By the formation of a layer of cambium between the bundles (interfascicular cambium), a complete ring is formed, and a regular periodical increase in thickness results from the development of xylem on the inside and phloem on the outside.". Is that enough to answer the question?
Answer: yes
