Diffusion is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. You are familiar with diffusion of substances through the air. For example, think about someone opening a bottle of perfume in a room filled with people.

What Are Some Examples of Active and Passive Transport? Some examples of active transport are endocytosis, exocytosis and the use of a cell membrane pump; diffusion, osmosis and facilitated diffusion are all examples of passive transport. In active transport, particles move from areas of low concentration to high concentration, while in passive transport, the particles move from areas of high concentration to areas of low concentration.

Epithelial cells use primary and secondary active transport , often in conjunction with passive diffusion through ion channels , to produce transcellular transport across epithelial tissues .
