Describe One Way How Plants Responds to Stimuli

Plants need sunlight to grow, hence they angle or move towards the source of light. This type of movement is called phototropism. Suppose a plant moves away from a source of light, it is called negative phototropism. But if plants grow towards the source of light, it is called positive phototropism.

The other type of movement that plants exhibit is called Thigmotropism, where movement occurs in response to physical touch or a stimulus. The touch-me-not plant exhibits thigmotropism when they are touched.
