What is growth towards water in plants called?

Answer and explanation

Correct answer: Hydrotropism

The governing concept is a plant tropic response to water. Directional growth of a plant organ toward a moisture source is called positive hydrotropism. Roots commonly show this response, helping them grow toward regions where water is available, although gravity and other stimuli may also influence their path. Thus option A is correct. Phototropism responds to light, chemotropism to chemicals, and thigmotropism to touch or contact.
