WebPhototropism is a plant's response to light. It has nothing to do with the direction of room growth. The stem may lean toward the sun (because of it's positive phototropism) but will still grow upward because of its negative geotropism. **If the light was below the plant, the roots would still grow downward. This is a good answer, though we ... WebIn other words, thigmonasty is the nastic movement of a plant part in response to touch. Thus, the stimulus in thigmonasty is the ‘touch’.

WebIn plant biology, thigmotropismis a directional growth movementwhich occurs as a mechanosensory response to a touch stimulus. Thigmotropism is typically found in twining plantsand tendrils, however plant biologists have also found thigmotropic responses in flowering plantsand fungi. This behavior occurs due to unilateral growth inhibition.[1] WebChemotropism: Plant movement in reaction to chemical stimuli is known as chemotropism. The growth response is positive chemotropism when it is directed toward the stimulus. When the growth response is away from the stimulus, it is called negative chemotropism. Example: Growth of pollen tubes towards ovules.

Thigmotropism is defined as the directional movement of plants in response to the stimulus of touch.
