Detailed explanation-1: -Thigmotropism is one example of tropism, which is the responding of a plant to environmental stimuli by growing towards or away from them. In other words, the reaction can be positive or negative. For instance, a stem can grow upwards towards the sun, and roots can grow away from an object in the soil.

Detailed explanation-2: -Thigmotropism is when plants grow in response to touch or contact with objects. For example, vines have small tendrils that curl around walls or trellises. Plants like this don’t usually have strong stems. So, thigmotropism helps them stay upright and keep growing.
