Which statement shows the correct relation between stimulus and response?
Answer and explanation
Correct answer: Light is the stimulus and bending of the stem is the response
A stimulus is a detectable change in the surroundings or inside an organism that can initiate a response. A response is the resulting action or change. In phototropism, light provides the directional stimulus, and the plant stem bends toward the light as its growth response. Therefore, option A correctly identifies both parts; the other pairings confuse organs, substances, and actions.
