Question

Does simple diffusion go to high to low or low to high

Answer 1

It goes from high to low. It is explained as it is trying to spread out or it is trying to be equal across a space.

Answer 2

From high to low.

Step-by-step explanation:

When we say "high to low" and "low to high", when talking about cells, diffusion, passive transport, etc. we are referring to the concentration of the solute in both sides of the biological membrane.

In simple diffusion, the molecules travel from a higher concentration to a lower concentration, in order to create a uniform environment.

The opposite of diffusion is osmosis, meaning that in osmosis the opposite happens; in this case, molecules are "attracted" to the higher concentration side of a biological membrane, and travel to it.
