Plant source–sink relationships, phloem loading and unloading, sieve-element transport, pressure-driven bulk flow, and regulatory context.
Visual lesson 06
Source-sink integration
Connect mature exporting leaves with changing sinks such as expanding shoots, roots, flowers, and developing seeds to understand how phloem allocation shifts through development.
Primary visual specification
Whole-plant source-sink allocation network
Create an academically accurate whole-plant source-sink allocation network for the Source-sink integration lesson. Use neutral studio lighting or clean academic illustration conventions, realistic botanical proportions, readable labels where needed, no yellow cast, and no decorative elements that compete with the teaching objective.
