(N/A) The movement of the leaves of a sensitive plant (e.g.,$Mimosa$ $pudica$) is known as a nastic movement. This movement is independent of the direction of the stimulus and occurs due to a rapid loss of water (turgor pressure) in the cells upon touch.
In contrast,the movement of a shoot towards light is a phototropic movement. This is a directional growth movement that occurs due to the unequal distribution of plant hormones,specifically auxins,in response to light.
While nastic movements are rapid and reversible,tropic movements are generally slower and involve actual growth of the plant part.
