Biology Quiz: Diffusion and Osmosis

Osmosis requires energy, while diffusion does not.

Osmosis does not involve a concentration gradient.

Diffusion involves water only, while osmosis involves all solutes.

Diffusion can occur in all states of matter; osmosis only occurs in liquids. (correct)

Active transport of solutes from the root hair.

Diffusion of water from root hair to the soil.

Osmosis due to concentration differences of solutes. (correct)

Pressure exerted by the xylem as water rises.

It occurs when molecules move from high to low concentration. (correct)

Larger molecules diffuse faster than smaller molecules.

Molecules will only diffuse in the presence of each other.

It requires energy in the form of ATP.
