Explain the process of passive transport.

• Passive transport is the movement of molecules from an area of low concentration to an area of high concentration.

• Passive transport is the movement of molecules through protein channels in the cell membrane.

• Passive transport is the movement of molecules across a cell membrane with the use of energy.

• Passive transport is the movement of molecules across a cell membrane without the use of energy.
