FoundationWhat is a tropism?
Need a small nudge?

The response direction is related to the stimulus direction.

UnderstandingWhy does a young shoot commonly bend toward one-sided light?
Need a small nudge?

Curvature results when the two sides of the shoot elongate at different rates.

ApplicationA germinating root is turned horizontally in uniform moisture. Which response is most expected?
Need a small nudge?

Roots commonly grow in the same direction as gravity.

InterpretationWhich comparison correctly distinguishes thigmotropism from thigmonasty?
Need a small nudge?

Separate growth curvature from rapid reversible movement.

ConnectionA root encounters a lateral gradient from dry soil to soil with higher water potential while gravity still points downward. Which statement is most defensible?
Need a small nudge?

Roots integrate more than one directional cue.
