If a root receives signals from the direction of water and from gravity, what idea does this question test?
Answer and explanation
Correct answer: Multiple stimuli can jointly affect the direction of plant growth
Roots can show hydrotropism, a growth response to water, and geotropism, a growth response to gravity. When both stimuli are present, their directions and strengths may jointly influence the final growth pattern. Thus the question tests the combined effect of multiple stimuli, making option A correct. Plants do respond to stimuli, roots are not guided only by sound, and they do not use animal-like nerve cells.
