Question

What are the differences between Tropism and Nastic Movement?

Answer 1

A tropic movement is the type of biological phenomenon, indicating growth or turning movement of a biological organism, usually a plant induced by some external stimuli. This response is dependent on the direction of the stimulus while as the nastic movement is the type of movement that is not governed by the direction of the stimulus. Whatever be the direction of stimulus, the movements always occur in a particular direction.
