What is Osmosis?
Osmosis is the net movement of water molecules from a region of higher water potential to a region of lower

Diffusion is the (Net) movement of particles from an area of high concentration to an area of low concentration
What is the concentration gradient?
A concentration gradient is when the concentration of particles is higher in one area than another.
