- Diffusion is the movement of particles from an area of high concentration to an area of low concentration. Diffusion is not to be confused with osmosis, which is the movement of water through a semi-permeable membrane.

Diffusion and Passive Transport Diffusion is the tendency of molecules to spread into an available space. Without other outside forces at work, substances will diffuse from a more concentrated environment to a less concentrated environment. Passive transport is the diffusion of substances across a membrane. This is a spontaneous process and cellular energy is not expended. Molecules will move from where the substance is more concentrated to where it is less concentrated.

Diffusion Diffusion. Dissolved substances have to pass through the cell membrane to get into or out of a cell. Diffusion is one of the processes that allows this to happen.Diffusion diffusion: The movement of particles (molecules or ions) from an area of higher concentration to an area of lower concentration occurs when particles spread.They move from a region where they are in high concentration to a region where they are in low concentration.Diffusion happens when the particles are free to move. This is true in gases and for particles dissolved in solutions.Particles diffuse down a concentration gradient, from an area of high concentration to an area of low concentration.iffusion. Dissolved substances have to pass through the cell membrane to get into or out of a cell. Diffusion is one of the processes that allows this to happen.

- 1 Contagious diffusion is the rapid, widespread diffusion of a characteristic throughout the population. 2  Ideas that are spread through contagious diffusion are spread throughout the population like the flu would. 3  It starts with one person or place and it keeps spreading.

Diffusion Diffusion is the net movement of molecules or atoms from a region of high concentration (or high chemical potential) to a region of low concentration (or low chemical potential). This is also referred to as the movement of a substance down a concentration gradient. A gradient is the change in the value of a quantity (e.g., concentration, pressure, temperature) with the change in another variable (usually distance).

General Chemistry/Diffusion and Effusion Diffusion [edit]. Diffusion of KMnO4 in water. Diffusion is the process of a substance spreading out to evenly fill its container or environment. In a solution, a concentrated solute diffuses to spread evenly in its solvent. In air, gas molecules diffuse to mix thoroughly. Substances diffuse from areas of high concentration to low concentration.

- Diffusion is defined as the the movement of molecules from an area of high concentration to an area of low concentration by random molecular motion. Net diffusion eventually results in a uniform distribution of the solute molecules.

A-level Biology/Biology Foundation/cell membranes and transport Diffusion [edit]. Diffusion is defined as the net motion of a substance from an area of high concentration to an area of low concentration, 'down a concentration gradient' . Factors which affect diffusion; 1  How steep the concentration gradient is. 2  Concentration gradient is the ratio of molecules on one side of the membrane to the other, many on one side compared to few on the other will result in a faster net rate of diffusion. 3  Temperature.

Diffusion An example of diffusion in biological system is diffusion of oxygen and carbon dioxide across the alveolar-capillary membrane in mammalian lungs. Diffusion may be a simple diffusion or facilitated diffusion. A simple diffusion is one in which that occurs unassisted. Facilitated diffusion in contrast is an assisted diffusion in a way that it requires a carrier molecule. For instance, polar molecules diffuse across a cell membrane through carrier molecules embedded in the cell membrane.

Where in the human body does diffusion occur? Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.smosis is the diffusion of water across a semi-permeable (or differentially permeable or selectively permeable) membrane. The cell membrane, along with such things as dialysis tubing and cellulose acetate sausage casing, is such a membrane. The presence of a solute decreases the water potential of a substance.

Diffusion and Passive Transport Public Domain Image. Diffusion is the tendency of molecules to spread into an available space. Without other outside forces at work, substances will diffuse from a more concentrated environment to a less concentrated environment. Passive transport is the diffusion of substances across a membrane. This is a spontaneous process and cellular energy is not expended.

- Oxygen is passed from lungs to cells by a process of diffusion. The carbon dioxide excreted by the cells is diffused to the lungs. Diffusion is also central to the process of excretion. When there is excess water it is diffused to the kidneys, and when there is less water it is diffused back to the body.iffusion or passive transport occurs in living organisms without any additional input of energy. The process simply occurs if the concentration gradient is such that there is a concentration difference of a particular substance outside and inside a cell membrane.

diffusion In the process of diffusion of a single solute, a concentration of molecules on one side of a membrane (top) will move through a membrane (center) until there is equilibrium on both sides (bottom). (dĭ-fyo͞o′zhən)

Osmosis and Diffusion Diffusion is the movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. A good example of diffusion is food colouring. If you place a drop of red food colouring in a beaker of water eventually the entire beaker of water will have a red tint. The food colouring moved through the water until it was equally distributed throughout the beaker.

Diffusing capacity The term may be considered a misnomer as it represents neither diffusion nor a capacity (as it is typically measured under submaximal conditions) nor capacitance. In addition, gas transport is only diffusion limited in extreme cases, such as for oxygen uptake at very low ambient oxygen or very high pulmonary blood flow.

Mass diffusivity For other uses, see Diffusivity (disambiguation). Diffusivity or diffusion coefficient is a proportionality constant between the molar flux due to molecular diffusion and the gradient in the concentration of the species (or the driving force for diffusion). Diffusivity is encountered in Fick's law and numerous other equations of physical chemistry.

Gas Exchange Principles of Gas Exchange The random movement of molecules is called diffusion. Although individual molecules move randomly, a substance can have directed movement, or net diffusion. The net diffusion of a substance occurs because of a difference in its concentration, or gradient , along its course.
