All 5 cards in this deck

Which of diffusion, osmosis and active transport can move a substance against its concentration gradient?

Active transport only.

Which transport process moves only water molecules?

Osmosis.

True or false? Osmosis and diffusion both require energy from respiration, but active transport does not.

False. Diffusion and osmosis are passive; only active transport requires energy from respiration.
