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.
Vascular Bundles
Strands of specialized tissue in plants that contain xylem and phloem for the transportation of water, nutrients, and sugars.
Apical Meristem
A region of plant tissue, found at the tips of roots and shoots, responsible for primary growth.
Woody Bark
The tough, protective outer layer of a woody plant or tree, consisting of dead cells and providing support and protection.

Final Answer :
D
Explanation :
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.
