Question

Differences between nastic, tactic and tropic movement in plants

Answer 1

Tactic movements are types of locomotion movements that are caused by certain unidirectional stimuli from outside. ... Nastic movements are different than the tropic movements because tropic responses depend on the stimulus direction, whereas nastic movement direction is independent of the position of stimulus.

Answer 2

Tactic movements are types of locomotion movements that are caused by certain unidirectional stimuli from outside. ... Nastic movements are different than the tropic movements because tropic responses depend on the stimulus direction, whereas nastic movement direction is independent of the position of stimulus.

Answer: Both tropic and nastic movements are influenced by environmental cues. ... In tropic movements, there is directional growth of a plant, or part of a plant, in response to an external stimulus such as gravity or light. So the direction of the stimulus controls the orientation of growth.
