Question

Radial vascular bundles are those in which

• A. Xylem is surrounded by phloem
• B. Phloem is surrounded by xylem
• C. Xylem and phloem occur on the same radius
• D. Xylem and phloem are found on different radii

Answer 1

The correct option is D Xylem and phloem are found on different radii

A.xylem is surrounded by phloem – hadrocentric or amphicribal vascular bundles

B.phloem is surrounded by xylem – Leptocentric or Amphivasal vascular bundles.

C.xylem and phloem occur on the same radius – collateral vascular bundle.

D.xylem and phloem are found on different radii – Radial vascular bundle.

So, the correct option is ‘xylem and phloem are found on different radii’.
