Solution

Thigmotropism	Thigmonasty
It is a directional movement of plant parts in response to touch.	It is a non-directional movement of plant parts in response to touch.
Example: Bitter gourd	Example: Mimosa pudica

Bitter gourd exhibits thigmotropism as its tendrils show directional movement towards the things they happen to touch.
On the other hand, Mimosa pudica exhibits thigmonasty as its leaflets show non-directional movement in response to touch.

Concept: Tropic Movements in Plants
