Osmosis is the movement of molecules through a selectivly permeable membrane.
Osmosis aims to equalize solute concentrations on the two sides of the membranes.
The equalizing of solute concentrations is know as Diffusion.
Osmosis may occur when there is a semi-permeable membrane submerged in water, and the water molecules pass through the membrane from an area of low concentration to high concentration or vice versa.
Hypotonic Solutions occur when there is a higher amount of solute outside the cell that is moving into the cell.
A Hypertonic solution is having greater solute concentration inside the cell that is displacing outward of the cell.
Isotonic solution is when the cell is in equalibrium with its surrounding enviroment.
These are all forms of diffusion.
Facilitated diffusion is the transfering of molecules from either side through the membrane via protein channels.
