Answer
Differences between between thigmotropic and chemotropic movement are:
| Thigmotropic Movement | Chemotropic movement |
|---|---|
| The growth movement of plant parts in response to touch stimulus is called thigmotropic movement. | The growth movement of plant parts in response to nutrient or chemicals is called chemotropic movement. |
| Example — Plants such as sweet peas, Cuscuta and vines have tendrils which coil around other plants in response to one sided contact or touch. | Example — Growth of pollen tube towards the sugary substance secreted by the stigma of the flower. |
