Thigmotropism is a growth response of plants to touch or physical contact. This phenomenon allows plants to adapt to their environment by growing towards or around objects. For example, climbing plants like vines exhibit thigmotropism by wrapping around supports, which helps them reach sunlight and stabilize themselves. This response is triggered by specialized cells that sense touch, leading to changes in growth patterns. Tendrils, which are slender, coiling structures, are a common example of thigmotropism in action. By responding to physical stimuli, plants can optimize their growth and survival in various habitats.
