What is the difference between a dicot root and a monocot root in cross-section?
Original Khojo Papers practice question — not from a past board paper.
Answer
A dicot root has two to four xylem bundles arranged radially with the phloem between them, a well-developed pith that is small or absent, and a cambium that appears later and allows secondary growth. A monocot root has many xylem and phloem bundles, a large well-developed pith, and no cambium, so there is no secondary growth.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
In both, the xylem is exarch, with the protoxylem towards the outside.
