Thigmotropism is a growth response of a plant in response to touch or contact. It can be positive (growing towards the stimulus) or negative (growing away from the stimulus).

Here are some examples:

* Venus Flytrap: The trap of a Venus Flytrap rapidly closes when the sensory hairs inside the trap are touched.

* Climbing Vines: Vines like ivy and morning glory use tendrils to wrap around objects they touch, helping them climb.

* Mimosa Pudica: This plant is also known as the "sensitive plant" and its leaves fold up quickly when touched.
