Quizplus · Accepted Answer

Shoots grow up due to positive phototropism (in response to light) and negative gravitropism (against gravity). Meanwhile, roots grow down due to negative phototropism and positive gravitropism. Thigmotropism refers to the directional growth of a plant in response to touch or contact with an object, such as a vine wrapping around a support or thorns growing in a certain direction to deter herbivores.
