• Diffusion
• Active Transport
• Facilitated Diffusion
• Osmosis

A cell is 95% water and 5% salt. It is placed into a beaker with a 10% salt solution. What will happen to the cell?

• water will diffuse out of the cell and it will shrink

• water will diffuse into the cell and it will swell

• No change

• the cell will diffuse water and salt equally across the membrane

The movement of molecules across a membrane from high concentration to low concentration is called:

• Osmosis
• Diffusion
• Endocytosis
• Active Transport

Active Transport requires ______ to transport materials across the cell membrane.

• ATP

• Glucose

• Na+

• K+

When material passes into and out of a cell at equal rates and there is no difference in concentration between the inside and outside of the cell, the cell is in a state of...

• dynamic equilibrium

• diffusion

• osmosis

• active transport
