Plant source–sink relationships, phloem loading and unloading, sieve-element transport, pressure-driven bulk flow, and regulatory context.
Visual lesson 05
Damage & recovery
See how bending, crushing, pruning, and breakage affect support and transport and why damage severity matters.
Interactive academic visual
Stem damage & recovery
Severity depends on vascular continuity, tissue loss, support and plant conditionIntact stem
An undamaged stem maintains mechanical support and continuous xylem and phloem pathways.
