Diffusion and Osmosis

Diffusion and Osmosis

Diffusion and Osmosis. KEY CONCEPT Materials move across membranes because of concentration differences. Passive transport does not require energy input from a cell. Molecules can move across the cell membrane through passive transport. There are two types of passive transport. diffusion.
