You Are Studying the Growth Responses of Plants That Are

You are studying the growth responses of plants that are heavy with ripening fruit in small well-sealed environmental chambers. In the "treatment" chamber the stems are periodically pushed by a mechanical arm, which causes the stem to sway back and forth for a long period due to the heavy fruit. In the "control" chamber the crown is just as heavy, but the stem is not perturbed. When you examine the new stem-growth that develops during the experiment you find:

A) in the "treatment," internodes are much more elongated than in the "control."
B) in the "treatment," internodes are much less elongated than in the "control."
C) internodes in both "treatment" and "control" plants are highly elongated.
D) internodes in both "treatment" and "control" plants have compact internodes.
