NEET BIOLOGY

Detailed explanation-1: -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: -The movement of plants in response to the stimulus of touch is called thigmotropic movement.

Detailed explanation-3: -The correct option is D. Thigmotropism. The movement of a plant due to touch is called thigmotropic movement (Thigmotropism).

Detailed explanation-4: -Thigmotropism is plant growth response to touch. An example of this tropism is the curling of a vine tendril around objects that it touches. This helps the plant securely position itself and keep growing, as these types of plants do not usually have a strong stem to keep themselves upright.

Detailed explanation-5: -Thigmotropism is the type of tropic movement which occurs in response to touch. Similarly, phototropism, chemotropism and hydrotropism occur in response to light, chemicals and water respectively.
