Diffusion moves molecules from greater concentration to lesser concentration.
However, since this is not my area of expertise, I searched Google under the key words "cells active passive transport" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. Thanks for asking.
