Question

An old trunk of Dalbergia tree would have maximum amount of

• A. Primary phloem
• B. Primary xylem
• C. Secondary xylem
• D. Secondary cortex

Answer 1

Answer: (C)

Secondary xylem

Cork cambium gives rise to the secondary xylem more than the secondary phloem as it increases the girth of the trunk and helps in the secondary growth that provides strength to the tree.
So the correct option is 'Secondary xylem'.
