Bitesize Transport Quiz

A glucose molecule diffuses out of a cell through the selectively permeable cell membrane. What is this an example of?

• Active Transport

• Osmosis

• Passive Transport

The diagram shows three animal cells. Pairs of red circles represent oxygen molecules. Between which two cells is there the highest oxygen concentration gradient?

• One and Two

• Two and Three

• One and Three

The diagram shows three plant cells and the solute concentrations of their cell solutions.

Between which cells will the movement of water by osmosis occur?

• From three to one

• From one to three

• From one to two

What may happen to red blood cells placed in distilled water?

• They may burst

• They may become turgid

• They may shrink

What structure can prevent a plant cell from bursting when it gains water by osmosis?

• Cell Membrane

• Cell Wall

• Vacuole

What happens to plant cells that are placed in distilled water?

• They will burst

• They will become plasmolysed

• They will become turgid

The diagram shows a cube of potato, (P), in a beaker containing a solution containing a very high sugar concentration (R). After one hour, what will have happened to cube P?

• It will gain mass

• It will lose mass

• It will remain the same

What could cause a plant cell to become plasmolysed?

• Gain of water
