The Plant Superhighway

Cross-section through the stem of Dracenea illustrating cellular relationships within the vascular tissue. Resources like water and nutrients traverse the plant via vascular bundles that are made up of many different cell types. Xylem fibers transport water and dissolved nutrients, while phloem fibers allow substances like sugar to move through the plant.
