Plant source–sink relationships, phloem loading and unloading, sieve-element transport, pressure-driven bulk flow, and regulatory context.
Visual lesson 03
Phloem transport
Follow movement of photosynthate from source tissues toward growing and storage sinks throughout the plant.
Interactive academic visual
Phloem transport
Photosynthate moves from source tissues toward active sinksSource tissue
Mature photosynthetic leaves commonly export assimilated carbon when their production exceeds local demand.
