1 Answer

Answer :

(1) collateral Explanation: In the collateral type of vascular bundle, xylem and phloem are arranged side by side on the same radius. This may be either open or closed. Usually xylem is seen towards the inner side and phloem towards outer side. The collateral vascular bundle is also known as conjoint.
