Answer
Some specific movements of the plants do not lead to the plant growth. Such movements are called growth-irrelevant movements.
In the plant called venus fly trap, there is a trap that appears and smells like flowers and deceives insects. When an insect visits the flower-like trap, the trap closes up and the trapped insect is digested by the plant.
Fibrils present on the leaves of the insectivorous plant Drosera, bend inward as soon as an insect lands on the leaves and surround the insects from all sides.
In Balsam, the ripened fruit dehisces (bursts-open) at the right time to disperse the seeds.
