What is passive transport?

Passive transport is a type of cellular transport that does not require energy input from the cell. It relies on the natural movement of molecules from an area of high concentration to an area of low concentration, known as diffusion. Passive transport includes processes such as simple diffusion, facilitated diffusion, and osmosis.

Passive transport is a process where molecules move from an area of high concentration to an area of low concentration without the use of energy. This process does not require cellular energy and can occur through diffusion or osmosis.
