Definition:

1. Active transport is a process that involves movement of molecules from a region of lower concentration to a region of higher concentration against a gradient with the use of external energy.
2. Passive transport is the movement of molecules within and across the cell membrane from lower concentration to higher concentration without using energy.

Active transport	Passive Transport
It requires energy in the form of ATP.	It does not require energy.
It involves movement of large molecules.	It involves movement of small or water molecules.
