Question

Identify the correct statement for monocotyledonous root

• A. Pith is large and well developed
• B. No secondary growth
• C. Polyarch condition
• D. All of the above

Answer 1

The correct option is A Pith is large and well developed

D. All of the above

EXPLANATION: Monocotyledonous root contains epidermis, cortex, endodermis, pericycle, xylem, phloem and a pith. Pith is extended into the flowering stems and roots. Pith in monocotyledonous root is large and well developed. In monocotyledonous root secondary growth does not occur, because of the absence of cambium in vascular bundle in between xylem and phloem. But there is exceptions like in Draceana. In Draceana secondary growth is seen. In polyarch condition many bundles of xylem is present. In monocotyledonous root polyarch condition is seen.
