When light comes from one side, the stem bends towards which side?
Answer and explanation
Correct answer: Towards light
A green stem generally shows positive phototropism, meaning it grows toward a source of light. Light causes auxin to redistribute toward the shaded side, where cells elongate more rapidly; this unequal growth bends the stem toward the illuminated side. Hence option A is correct. B describes the opposite response, while C and D refer to directions unrelated to the stated light stimulus.
