If a plant root grows towards water and the stem grows towards light, which conclusion is correct?
Answer and explanation
Correct answer: The root shows hydrotropism and the stem shows phototropism
Hydrotropism means directional growth in response to water, so a root growing toward moisture demonstrates hydrotropism. Phototropism means directional growth in response to light, so a stem bending or growing toward light demonstrates phototropism. Therefore option A correctly names both responses. The other options confuse growth responses with life processes or deny the observed responses.
