Visual lesson 08
Floral meristem branching & photoperiod
Compare adult long-day and short-day shoot apices to see how short-day exposure can increase reproductive branching and reduce internode extension as the inflorescence condenses, while keeping individual flower initiation conceptually distinct from this architectural transition.

Long-day versus short-day shoot-apex branching and internode modelStart with the highlighted plant system as the anatomical context. Then compare the lesson observations with the evidence sources and knowledge check below so structure, process, and whole-plant consequences stay connected.- Plant system
