Answered 0/5
FoundationWhich hormone class is most directly associated with cell elongation in shoot phototropism?
Need a small nudge?

This hormone redistributes across a lit shoot and contributes to differential elongation.

UnderstandingWhich comparison between gibberellins and abscisic acid is most accurate?
Need a small nudge?

One commonly promotes growth resumption; the other often supports restraint and water conservation.

ApplicationA horticulturist wants to delay yellowing in detached leaves for an experiment. Which hormone class is most closely associated with delaying leaf senescence?
Need a small nudge?

This class also promotes cell division.

InterpretationWhy is “ethylene alone causes every leaf to fall” an inaccurate explanation of abscission?
Need a small nudge?

Plant responses often arise from signal interactions rather than a solitary switch.

ConnectionA drought-stressed plant closes stomata while a dormant seed of the same species remains ungerminated. Which hormone can contribute to both responses?
Need a small nudge?

Look for a signal involved in water conservation and dormancy.
