Vedclass · Answer

(C) Diffusion is a passive process,meaning it does not require the expenditure of $ATP$ energy.It occurs along the concentration gradient,where molecules move randomly from a region of higher concentration to a region of lower concentration.Diffusion is a slow process and is not dependent on a living system.Because it relies on random molecular movement,it is effective only over short distances and becomes extremely slow and inefficient for long-distance transport in plants.
