No cellular energy is needed in the Passive transport.
Explanation:
A movement of atomic molecules and ions throughout the cell membrane is known as passive transport. In this transportation of molecules no cellular energy is used.
As this movement is influenced by the tendency to grow as entropy, the energy is not in need unlike the active transport. Its rate depends on the permeability of cell membrane. There are four types of passive transport- facilitated diffusion, simple diffusion osmosis or filtration.
