Detailed explanation-1: -Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes. Instead of using cellular energy, like active transport, passive transport relies on the second law of thermodynamics to drive the movement of substances across cell membranes.

Detailed explanation-2: -The movement of molecules across a membrane without the input of energy is known as passive transport. When energy (ATP) is needed, the movement is known as active transport.

Detailed explanation-3: -Facilitated diffusion is the passive transportation of ions or molecules across the cell membrane through specific transmembrane integral proteins.

Detailed explanation-4: -Passive transport, also known as passive diffusion, is a process by which an ion or molecule passes through a cell wall via a concentration gradient, or from an area of high concentration to an area of low concentration.

Detailed explanation-5: -There are three passive transportation methods-diffusion, facilitated diffusion and osmosis.
