Question
What differentiates open vascular bundles from closed
vascular bundles in plants?Solution
Open vascular bundles are characterized by the presence of cambium tissue, which is a layer of actively dividing cells located between the xylem and phloem. The cambium allows for the formation of secondary xylem (wood) and secondary phloem, enabling the plant to grow thicker over time. This feature is common in dicotyledonous plants.
