During simple diffusion…
A. solutes do not cross the membrane
B. the cell uses energy to push solutes across a membrane
C. solutes move through protein channels
D. solutes move from areas of high solute concentration to areas of low solute concentration
How is the mitochondria different from the chloroplast?
A. The mitochondria has its own DNA while the chloroplast doesn’t
B. The mitochondria converts sugars to ATP while the chloroplast stores solar energy in sugars
C. The mitochondria is in the cytoplasm while the chloroplast is in the nucleus

You put a cheek cell in a highly concentrated sugar solution. What should happen to the cheek cell?
A. It should swell – the solution outside is hypotonic.
B. It should swell – the solution outside is hypertonic.
C. It should shrink – the solution outside is hypertonic.
D. It should swell – the solution outside is isotonic.
Why do solutes move through protein channels in facilitated diffusion?
