17. (Rem) Define: diffusion, osmosis, active transport, passive transport.

-Diffusion is movement of material from an area where molecules are crowded to an area where they’re less crowded.

-Passive transport is movement of materials through a membrane without the use of energy.

-Active transport is movement of materials through a membrane using energy.

-Osmosis is movement of water through a membrane.
