An increase in girth and decrease in height of a shoot is in response to which of the following environmental stimuli?

Question

Quizplus · Accepted Answer

Wind causes plants to experience mechanical stress, leading to an increase in girth (thickness) as the plant strengthens itself against the force of the wind. This phenomenon is part of a plant's thigmomorphogenetic response. Height may decrease as energy is diverted to increasing girth and strengthening the structure rather than vertical growth.
