Plants use sunlight to produce sugar molecules in their leaves. Some of this sugar is needed by cells in the roots. Would you expect plants to rely on diffusion to transport the sugar molecules from leaves to roots, and why?
A. Yes, because diffusion will happen naturally, so the plant does not have to spend energy on it.
B. Yes, because all materials in living tissues move by diffusion.
C. No, because it would take too long for the sugar molecules to diffuse that far.
D. No, because diffusion only operates over small distances, not over long distances.
