The ..... regulates what enters and leaves a cell.

facilitated diffusion allows the movement of which particles through the channel protein?

• glucose

• ions

• water

• oxygen

Feeling thirsty after having salty food is an example of:

• diffusion

• passive diffusion

• osmosis

• endocytosis

unicellular cells do NOT mostly have to only rely on diffusion for their transport systems.

• false

• true

villi absorb ....... through diffusion as a requirement.

• sugar

• CO2

• oxygen

• fatty acids

What type of cellular transport uses energy?

• passive

• active

Permeable means....

• things can pass through

• something is permanent

• the concentration levels are different

• expanding

How long does diffusion last?

• until particles disappear from the system

• until all particles have left to one region to create a high concentration

• until the concentration of particles is equal

• until particles blow up
