• solvent
• solute
• solution

The difference in the concentration of a substance from one location to another is called a/an

• diffusion

Passive transport requires no

• concentration gradients

• osmosis

• motion

• energy

This example of passive transport is the diffusion of water.

• osmosis
• concentration gradient
• isotonic
• facilitated diffusion

In facilitated diffusion, molecules move

• Down a concentration gradient
• Against a concentration gradient

Facilitated diffusion is beneficial because

• some molecules cannot pass through the phospholipid bilayer

• often times carbohydrates are sent to the membrane and are used to assist molecules to go through

• it allows for you to use energy to move things in and out of a cell

• it helps to move things from low to high

• all of the above
