How can you identify a monocot and dicot stem give reason?

Monocot and dicot stems can be identified by their vascular arrangements. In monocots, vascular bundles are scattered throughout the stem, while in dicots, they are arranged in a circular pattern. Additionally, monocots typically have a more fibrous root system and tend to have parallel leaf venation, whereas dicots have a taproot system and net-like leaf venation. These structural differences reflect their evolutionary adaptations and roles in plant growth.
