Answer:

Explanation:

Active cellular transport:

  • It is the movement of molecules against the concentration gradient  (from low concentration to high).
  • Active transport requires expense of energy supplied by ATP.
  • It is a rapid way to transport of large sized molecules.

Passive cellular transport:

  • It is the movement of molecules along the concentration gradient (from high concentration to low).
  • Passive transport does not require expense of energy.
  • It is a slow process and small sized molecules get transprorted.
