Osmosis Osmosis is the net movement of water molecules over a partially permeable membrane from an area of less osmotic potential to an area of more negative.

Chapter 3. Passive Transport  Diffusion – molecules move spontaneously (no energy used) from an area of high concentration to an area of low concentration.

PASSIVE TRANSPORT Movement of molecules across a membrane that requires no energy and always occurs down a concentration gradient Types of passive transport.
