What is facilitated diffusion?

• Transport that uses proteins to help move molecules across the membrane. 
• Movements of substances through a membrane. 
• When molecules spread from High to Low concentration on their own. 
• When pressure pushes something through a membrane. 

This is a ____.

• Golgi body
• plasma membrane
• lysosome
• cell wall

Which process involves the movement of molecules from high concentration to low concentration?

• Endocytosis
• Active transport
• osmosis
• phagocytosis

if you put a plant in salt water it will ...

• swell because water diffuses into the cells
• swell because water diffuses out of the cell
• shrivel because water diffuses out of the cell

Two different solutions are separated by a membrane permeable only to water. How will molecules move?

• solutes will move by dissolving
• water will move by active transport
• solutes will move by osmosis
• water will move by osmosis

Your gums are swollen. How will rinsing with warm salt water help the swelling?

• swollen gums will absorb the salt
• salt lowers the temp
• salt goes against the concentration gradient
• water in the gums has diffused out of the cells

Solutes move against the concentration gradient, therefore energy is needed. 

• Passive Transport
• Active Transport
