In monocots, how are vascular bundles arranged in the stem?

• A. Distributed throughout the stem (not in a ring)
• B. Form a clear ring around the stem
• C. Concentrated in a single central bundle
• D. Absent in monocots

Answer: (A)

Monocot stems have vascular bundles scattered throughout the stem rather than arranged in a ring. This means the xylem and phloem appear in multiple bundles located within the ground tissue, not forming a circular vascular cylinder. This contrasts with dicot stems, where bundles commonly organize into a complete ring around the stem, supporting secondary growth. So the vascular tissue in monocots is distributed throughout the stem, not centralized or absent.
