Final answer:
The statement about diffusion using cellular energy is not true; diffusion does not require cellular energy as it is a passive transport process.
Step-by-step explanation:
The statement that is not true of diffusion is: Uses cellular energy. Diffusion is a type of passive transport where molecules move from an area of higher concentration to an area of lower concentration without the use of cellular energy. This process can occur in both living and nonliving cells and involves the movement of substances both into and out of the cell. The driving force behind diffusion is the concentration gradient, which is a form of potential energy. Active transport, on the other hand, does require cellular energy because substances are moved against their concentration gradient.
