Unlike the <a href="./transpiration.md" class="link-internal">transpiration stream</a>, which moves passively from roots to shoots driven by evaporative tension, phloem translocation is active, energy-dependent, and bidirectional. Sugar moves from photosynthetic leaves (sources) downward to roots, storage organs, and developing tissues (sinks), and also moves upward from storage organs mobilizing reserves during growth or reproduction. Translocation velocities are rapid — 50 to 100 centimeters per hour — much faster than diffusion alone could achieve.</p>
