Plants have two types of movement :

1. Directional movement - Movement is directed towards the response to the stimulus. The stimulus can be either light, water or gravity. Such movements are called tropic movements. For example - Pototropism ( plants grow towards light and light is the stimulus or hydrotropism where plants grow towards the water and water here is the stimulus.)

2. Non-directional movement - Non-directional movement of the plant in response to an external stimulus. It is independent of growth and communicates via electrical chemical signals. For example, In touch-me-not plant whenever someone toches the leaves, the leaves get folded and here, response to touch is a stimulus.
