membrane.
How PASSIVE Transport occurs:
Breakout #4
Passive transport generally happens through the process of
diffusion – _________________________ of molecules from
and area of __________ concentration to _____________
concentration
Osmosis can occur either into or out of the cell depending on the
concentration of the solute. . . .

moving ________ the concentration gradient
Diffusion is caused by the _____________ ______________
of molecules. They are __________________ in motion.
Facilitated Diffusion:
