Meaning and Definition
The directional growth movement of a plant or fungus in response to physical contact or touch stimulus.
In biology, a growth response where the direction of growth is determined by contact with a solid object; commonly observed in climbing plants, tendrils, and some fungi. In broader scientific contexts, sometimes used metaphorically to describe systems or organisms that orient themselves through contact.

Common Mistakes When Using “thigmotropism”
- Misspelling as 'thigmatropism' or 'thigmotropysm'.

- Using in non-biological contexts.
- Incorrect stress placement: stress is on 'mo' (thig-MO-tropism).
FAQ
Frequently Asked Questions
No. Thigmotropism is directional growth in response to touch, while thigmonasty is a non-directional movement (like the closing of a Venus flytrap) in response to touch.
No, thigmotropism is specific to plants, fungi, and some other sessile organisms. Animals exhibit different behaviours like thigmotaxis (movement toward or away from touch).
Negative thigmotropism is growth away from a touch stimulus. This is less common but observed in some roots that grow away from obstacles.
It enables climbing plants to find and attach to supports, maximising light exposure without investing energy in thick supportive stems. It's an adaptive trait for efficient growth.
The directional growth movement of a plant or fungus in response to physical contact or touch stimulus.
