Transport Review

What term is used to describe when two solutions have reached a balanced state?

• Hypotonic

• Tonicity

• Hypertonic

• Equilibrium

How are osmosis and diffusion similar processes?

• A both move solute molecules

• both move water molecules

• they move low to high concentrations

• both move high to low concentrations

Active transport goes against the concentration gradient. What does that mean?

• High to Low

• Low to High

When placed in a solution of 30% water 70% salt, what would happen to a cell that is 70% water?

• it will take in salt and swell

• it will take in water and swell

• it will lose water and shrink

• it will remain the same size

During osmosis

• water moves from high to low concentration
• large or oddly shaped molecules move across a cell membrane
• water moves when energy is used
• proteins are built

You put a cell into a solution, the cell grows. Is the solution hypotonic or hypertonic to the cell? 

• hypertonic
• hypotonic
• isotonic
• not enough information
