Solution

Plants have two types of movements, tropic movement and nastic movement.
The tropic movements are growth-dependent movements that are generated away or towards the stimulus.
The nastic movements are non-growth-dependent movements that are independent of the stimulus. The examples of nastic movements are as follows-
a. The Mimosa pudica leaves show movement when they are touched.
b. Pitcher plant shut when an insect sits on its leaves.
