Vedclass · Answer

(D) Plant movements are classified based on the nature of the stimulus and the direction of the response.$1$. Tropic movements are directional movements in response to an external stimulus (e.g.,phototropism).$2$. Nastic movements are non-directional movements in response to an external stimulus (e.g.,seismonasty).$3$. Tactic movements are locomotive movements of the whole organism or cell in response to an external stimulus (e.g.,chemotaxis).Since all three types of movements occur in response to external stimuli,the correct answer is $D$.
