If a plant root gets water on one side and light on the other, which tropisms best explain its direction of growth?

Answer and explanation

Correct answer: Hydrotropism and phototropism

The governing concept is tropic movement, in which a plant part grows directionally in response to an external stimulus. Growth towards water is hydrotropism, while a growth response related to light is phototropism; roots commonly show negative phototropism by growing away from light. Therefore option A identifies the relevant stimulus-based growth responses. Thigmotropism and chemotropism are caused by touch and chemicals, so option B does not match the stated stimuli.
