BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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.

Detailed explanation-2: -So, the correct answer is ‘Thigmotropism’

Detailed explanation-3: -Gravitropism, the growth of roots and shoots toward or away from the direction of gravity, has been studied for centuries. Such studies have not only led to a better understanding of the gravitropic process itself, but also paved new paths leading to deeper mechanistic insights into a wide range of research areas.

Detailed explanation-4: -Positive gravitropism occurs when roots grow into soil because they grow in the direction of gravity while negative gravitropism occurs when shoots grow up toward sunlight in the opposite direction of gravity.

Detailed explanation-5: -The fig tree shows a perfect example of gravitropism as the tree grows upside down based on the gravity.
