Compare active transport and diffusion in terms of their similarities and difference.
-Thanks for your help =)-
I can't really do your work for you, as this sounds as it needs to be an answer of some length. Some basic idea to work with:
Means of molecular transport; used by cells; affected by temperature
Diffusion depends upon concentration gradient, acitve transport does not; active transport requires energy; active transport involves carriers; diffusion involves random movement of molecules, whereas active transport involves directed movement; diffusion is two-way, active transport is one-way (at any given moment.
