You need to identify a plant but it is winter and the leaves, flowers, fruits, are not available. Your best clue to whether it is a monocot or a eudicot is to
A) inspect the stem for woody bark since only eudicots have woody tissue.
B) determine if there is an apical meristem at the tip of the plant, which indicates it is a monocot.
C) determine if the roots lack phloem and xylem, which indicates a monocot.
D) cut the stem and if the vascular bundles are scattered in the stem, it is a monocot.
E) cut the stem and if the vascular bundles are in a distinct ring, it is a monocot.

Monocots typically have scattered vascular bundles in their stems, whereas eudicots (dicots) have their vascular bundles arranged in a distinct ring. This structural difference is a reliable way to distinguish between the two groups when other features are not available.
