Visual lesson 08

Hormones, sugars & bud outgrowth

Use general flowering-plant evidence to connect auxin transport in the main stem with cytokinin, strigolactone, sugars, light, and bud-local signaling, emphasizing that modern apical-dominance models integrate multiple interacting mechanisms rather than one direct hormone switch.

Primary visual specification

Node-centered auxin, cytokinin, strigolactone, sugar, and light interaction map

Create an academically accurate node-centered auxin, cytokinin, strigolactone, sugar, and light interaction map for the Hormones, sugars & bud outgrowth 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.
