Answer:
Passive transport is the movement of particulars across the membrane from area of <u>high</u> to an area of <u>low</u> concentration.
Explanation:
Passive transport is a transmembrane cellular transport mechanism characterized by the fact that it does not require energy.
What enables passive transport is the concentration gradient of a particle, which moves across the membrane from a site of high concentration to a site of low concentration.
