Question

Why is the folding up of the leaves of a sensitive plant on touching with a finger not a tropism?

Short Note

Solution

The folding up of leaves in a sensitive plant on touching is not a tropism because it is a non-directional movement. Tropism is a directional movement where the direction of the movement of the plant part is towards the stimulus.
