The difference between simple diffusion and facilitated diffusion is that facilitated diffusion moves materials from a lower to a higher concentration.
true / false.

False. The diferrence between simple diffusion and facillitated difussion has a relation between energy cost.

Explanation:

Facillitated diffusion requires energy expenditure, while simple diffusion can be done without expense. The diffusion facilitated also requires the use of transport proteins since the molecules that cross the membrane are larger than in the simple diffusion that allows the passage to smaller molecules.
