In passive transport, substances cross the membrane from an area of high concentration to an area of low concentration (move with the concentration gradient, or difference), without any expenditure of energy (ATP) by the cell. The term concentration refers to a substance's number of particles per volume unit.

Passive Transport doesn't use energy such as in osmosis and simple diffusion. Materials go from areas of high concentration to areas of low concentration. Passive Transport doesn't use energy such as in osmosis and simple diffusion. Materials go from areas of high concentration to areas of low concentration.

Passive transport high to low

In passive transport, substances move from an area of higher concentration to an area of lower concentration, down their concentration gradient. Depending on the chemical nature of the substance, we may associate different processes with passive transport. When small particles move from a high to a low concentration, it is called passive transport. This is the normal flow of materials. There are two types of passive transport. Osmosis is when water is moving high to low through a cell membrane, and diffusion is when all other small particles move from high to low concentration.
