If a plant root grows towards water, which response does it show?
Answer and explanation
Correct answer: Hydrotropism
A tropic movement is a directional growth response to a specific external stimulus. In this case, water or moisture is the stimulus, and the root grows toward it. Directional growth toward water is called positive hydrotropism. Phototropism is a response to light, chemotropism to chemicals, and thigmotropism to touch or contact. Therefore, the correct response is hydrotropism, option A.
