What is simple diffusion?

High concentration to low concentration

20

What is active transport?

Up a concentration gradient: requires energy

What is osmosis?

Diffusion of water down a concentration gradient

23

What is reverse osmosis?

Water is forced against it's concentration gradient

24

What is equilibrium?

When both sides of osmosis are filtered through exchange
