How is the movement of leaves of the sensitive plant different from the movement of a shoot towards light?

Question:

Answer:

Thigmotropism

Sensitive plant leaves's movement is independent of growth and is touch-sensitive; this is known as thigmotropism.

Phototropism

Phototropism is the shoot's growth-related inclination towards light.

‍

Thigmotropism	Phototropism
The sensitive plant’s movement is the nastic movement known as Thigmotropism.	The tropical movement that causes the shoot to incline towards light is Phototropism.
Exhibiting non-directional nastic motion with no particular path.	Exhibiting unidirectional where the stimulus originates.
Quick nastic motions	Extremely slow tropic motions
Leaves and petals, a plant's flat parts convey motion.	All plant sections exhibit these motions when the shoot gravitates towards light.
