1
Q
simple diffusion
A
small and nonpolar particles, such as oxygen, move directly through the cell membrane from high to low concentration
2
Q
facilitated diffusion
A
small polar particles are passively moved through protein channels from high to low concentration.
3
Q
osmosis
A
diffusion of water over a barrier
