Coiling of garden pea tendrils around any support is an example of:
Thigmotropism
Thigmotropism is the directional response of a plant organ to touch or have physical contact with a solid object. This directional response is generally caused by the induction of some pattern of differential growth. This phenomenon is clearly illustrated by the coiling of tendrils of garden pea around a support.
Thermotaxis- is the movement of an organism towards or away from the source of heat.
Thigmonasty - is the nastic response of a plant to touch or vibration. Thigmonasty differs from thigmotropism in that nastic motion is independent of the direction of the stimulus.
Thigmotaxis - a change in direction of locomotion in a motile organism or cell made in response to a tactile stimulus.
