Canopy Architecture Mastery Quiz — THC Living Plant Atlas

1Where is an axillary bud located?

AInside a trichome headBAt the root tip onlyCInside the seed coatDAt a node near the junction of a leaf and stem

2What is apical dominance?

AThe influence of the active shoot apex on the growth of lateral budsBThe movement of pollen through xylemCRoot-hair formationDTrichome cloudiness

3What is the main biological idea behind removing or partially disrupting the shoot apex?

ATurning phloem into rootsBRedistributing active shoot growth among remaining growing pointsCStopping photosynthesis permanentlyDChanging trichomes into stomata

4What does low-stress directional training primarily change?

AThe seed embryoBPollen geneticsCBranch orientation and canopy position while keeping tissues connectedDRoot-hair anatomy

5What do mainlining and screen-based canopy organization have in common?

ABoth are types of pollenBBoth occur only inside seedsCBoth eliminate all lateral growthDBoth organize the distribution of growing points across the canopy

6Why can PPFD differ within the same canopy?

ALeaf position, canopy structure, distance, and shading create different light zonesBEvery leaf always receives identical lightCOnly roots determine PPFDDPPFD is a seed trait

7How does stronger air movement around a leaf generally affect the still-air boundary layer?

AIt always makes the boundary layer thickerBIt turns stomata into rootsCIt has no relationship to leaf gas exchangeDIt tends to reduce boundary-layer thickness
