Morphology
The phrase is compositionally transparent: 'vascular' means relating to vessels (here sap-conducting tissues) and 'bundle' means a grouped collection, so a B1 learner who knows both words can infer it denotes a grouped strand of vascular tissue. Although the term is technical, its meaning follows directly from the constituents and is cross-linguistically analyzable.
Etymology
Vascular bundle comes from the image of many small vascular 'tubes' held together in a bundle, like a bunch of straws. That's why the term means a group of 'tubes' in stems and leaves that carry water and food through the plant.
