Regents Review Cell Transport and Biochemistry

Which type of passive transport focuses on the movement of water through the membrane?

• Facilitated diffusion

• Osmosis

• Diffusion

What term describes a solution that has the same solute concentration inside of and outside of the cell?

• Hypertonic

• Hypotonic

• Isotonic

The cell shrunk in size, which means it was placed in a ____ solution.

• Isotonic

• Hypertonic

• Hypotonic

What is the diffusion of water across a cell or semi-permeable membrane?

• Osmosis

• Diffusion

• Active Transport

• Passive Transport

In which case would a cell most likely shrink?

• when placed in a solution containing a high salt concentration

• when placed in a isotonic solution

• when placed in a solution containing a low pH

• when placed in a solution containing distilled water

Active transport requires energy because...

• The cell is moving something against a concentration gradient

• The cell is moving something with a concentration gradient

A student noticed that placing wilted lettuce in a bowl of cool water caused the lettuce to become more crisp and firm. What is the best explanation for his observation?

• Water moved into the lettuce cells by active transport.

• Water moved into the lettuce cells by osmosis.

• Salt moved into the lettuce cells by diffusion.

• Water moved out of the lettuce cells by osmosis.
