If a plant receives light from one side, where can auxin mostly collect?
Answer and explanation
Correct answer: On the shaded side
The governing concept is phototropism, the bending of a plant shoot toward light. In a shoot illuminated from one side, auxin is redistributed toward the shaded side. Its higher concentration there promotes greater cell elongation, so that side grows faster and the shoot bends toward the light. Therefore option A is correct; the other locations do not explain directional shoot growth.
