Diffusion – Definition, Examples and Types | Biology Dictionary
Diffusion is an important part of many biological and chemical processes. In biological systems, diffusion occurs at every moment, across membranes in every cell as well as through the body. For example, oxygen is at a higher concentration inside arteries and arterioles, when compared with the oxygen levels in actively respiring cells.

Simple diffusion and passive transport (article) | Khan Academy
In the process of diffusion, a substance tends to move from an area of high concentration to an area of low concentration until its concentration becomes equal throughout a space. For example, think about someone opening a bottle of cleaning ammonia in the middle of a room.

Importance of Diffusion in Organisms | Sciencing
Diffusion is the random but directional movement of molecules from a place of high concentration to a place of low concentration. This simple concept describes the process by which cells exchange toxic gases for life-sustaining gases. It also describes how nerve cells are able to send electrical signals to each other cells.

Diffusion refers to the movement of molecules from an area of high concentration to an area of lower concentration. Osmosis is a type of diffusion specifically for water molecules moving across a semi-permeable membrane. A concentration gradient is the difference in concentration of a substance between two areas, which drives or osmosis.

Diffusion – Introduction (video) | Khan Academy
AboutTranscript. Diffusion occurs when particles move from an area of high concentration to low concentration, creating a concentration gradient. This natural, energy-free process occurs due to the random movement of particles, with a higher chance of particles moving from the high concentration side.

1. Description of Diffusion and Osmosis. A water solution that contains nutrients, wastes, gases, salts and other substances surrounds cells. This is the external environment of a cell. The cell’s outer surface of the plasma membrane is in contact with this external environment, while the inner surface is in contact with the cytoplasm.
