Question #22e10

Osmosis, diffusion, and facilitated diffusion all three stand under passive transport. Passive transport is the transportation process which doesn't require energy ... energy like from Sun or mineral ions from soil.

Diffusion:

The net movement of particles from the higher concentration to a lower concentration down the concentration gradient until the equilibrium is reached.

Facilitated diffusion:

The net movement of the particles from a higher concentration to a lower concentration down the concentration gradient until an equilibrium is reached, but with the aid of membrane-bound proteins.

Osmosis

The net movement of water molecules from the higher concentration to a lower concentration down the concentration gradient until the equilibrium is reached through a partially permeable membrane.
