Question

Which type of vascular bundle is found in monocot stem?

• A. Conjoint, collateral, open, endarch
• B. Radial, open, diarch
• C. Radial, open, mesarch
• D. Conjoint, collateral, closed, endarch

Answer 1

The correct option is D Conjoint, collateral, closed, endarch

Xylem and phloem of the shoots of monocots and dicots are usually arranged opposite to each other in the vascular bundles so collateral. Cambium is absent so closed. Xylem is found towards the inner surface and phloem towards the outer surface; xylem and phloem lie on the same radius so collateral. Proto xylem is directed towards the center so endarch. Thus the correct answer is D.
