Detailed explanation-1: -In plant biology, thigmotropism is a directional growth movement which occurs as a mechanosensory response to a touch stimulus. Thigmotropism is typically found in twining plants and tendrils, however plant biologists have also found thigmotropic responses in flowering plants and fungi.

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.

Detailed explanation-3: -Thigmotropism describes plant growth in response to touch or contact with a solid object. Positive thigmostropism is demonstrated by climbing plants or vines, which have specialized structures called tendrils. A tendril is a thread-like appendage used for twinning around solid structures.

Detailed explanation-4: -Thigmotropism helps a plant grow and gain nutrition. When a climbing plant uses its tendrils to attach to a fence, it releases hormones that help the plant grow faster. Auxin is a hormone that is released by a climbing plant. It causes the parts of the plant that are not in contact with a surface to grow faster.
