vascular tissue
Internal transport system
Vascular tissue is the system of tubes that transports fluids through plants and animals.
In plants, xylem carries water up from roots while phloem distributes sugars from leaves.
In animals, blood vessels form vascular tissue.
The adjective vascular describes anything relating to these transport systems: vascular disease, vascular plants.
