Diffusion Biologists often use the terms net movement or net diffusion to describe the movement of ions or molecules by diffusion. For example, oxygen can diffuse through cell membranes so long as there is a higher concentration of oxygen outside the cell.

Science Quiz: Diffusion, Osmosis, Active and Passive Transport passive transport. the movement of particles from areas of high concentration to lower concentration and does not require any energy; can be described when someone is going down a hill, from high to low, and they do not need energy because they are just coasting; examples of passive transport are osmosis and diffusion.

What Is Diffusion in Science? Diffusion is the spontaneous movement of any type of particle or molecule from an area of high concentration to an area of low concentration, while osmosis is the diffusion of water across a semi-permeable membrane.

Difference between Active Transport and Passive Transport Diffusion, osmosis and facilitated diffusion are examples of passive transport. Particles which are soluble easily are transported via passive transport. It has an importance of maintaining equilibrium in the cell, waste is excreted out of the cell by means of passive transport, like carbon-dioxide or water.

- Again, this happens without energy, which is why it is known as passive diffusion. Example of Simple Diffusion In the cell, examples of molecules that can use simple diffusion to travel in and out of the cell membrane are water, oxygen, carbon dioxide, ethanol and urea.

Osmosis and Diffusion Some major examples of osmosis: 1  Absorption of water by plant roots. 2  Reabsorption of water by the proximal and distal convoluted tubules of the nephron. 3  Reabsorption of tissue fluid into the venule ends of the blood capillaries. 4  Absorption of water by the alimentary canal — stomach, small intestine and the colon.

- Example of Facilitative Diffusion. In the cell, examples of molecules that must use facilitated diffusion to move in and out of the cell membrane are glucose, sodium ions, and potassium ions. They pass using carrier proteins through the cell membrane without energy along the concentration gradient.

Trans-cultural diffusion 1 Indirect diffusion happens when traits are passed from one culture through a middleman to another culture, without the first and final cultures ever being in direct contact. 2  An example could be the presence of Mexican food in Canada, since a large territory (the United States) lies in between.here are five major types of cultural diffusion: 1  Expansion diffusion: an innovation or idea that develops in a source area and remains strong there, while also spreading outward to other areas. 2  This can include hierarchical, stimulus, and contagious diffusion.

- Simple diffusion is the net movement of substances from a region of high concentration to a region of low concentration.enerally, simple diffusion of water, gases, and other small, uncharged molecules across plasma membranes can occur in the absence of transport proteins. Facilitated diffusion involves plasma membrane and vacuolar protein channels and transporters.

Simple Diffusion: Definition & Examples In a solution or gas that has an area of high numbers of particles and an area of lower numbers of particles, the particles will diffuse, or move, from the area of higher to the area of lower concentration. This is known as simple diffusion, or passive diffusion. Simple diffusion does not require energy. Instead, it happens by random motion. Random motion is defined as movement that occurs by chance because there is no order or regular system by which the movements of the particles shift in a solution or gas.

What molecules which pass through the cell membrane by simple diffusion.? However some particles may be too large to pass through, in such cases active diffusion occurs where energy is used to transfer it using transfer proteins in the membrane structure. Example of substance that transferred via simple diffusion is water. Note that water transport is termed osmosis. Siavash · 3 years ago.

Contents: Active and Passive Transport Example of primary active transport, where energy from hydrolysis of ATP is directly coupled to the movement of a specific substance across a membrane independent of any other species. There are four main types of passive transport: osmosis, diffusion, facilitated diffusion and filtration.

Passive Transport - Taking the Easy Road Another big example of passive transport is osmosis. This is a water specific process. Usually, cells are in an environment where there is one concentration of ions outside and one inside. Because concentrations like to be the same, the cell can pump ions in an out to stay alive.

diffusion in chemistry, the spontaneous migration of substances from regions where their concentration is high to regions where their concentration is low. Diffusion is important in many life processes. It occurs, for example, across the alveolar membrane of the lung, which separates the carbon-dioxide-rich blood from the oxygen-rich air. Oxygen diffuses across the membrane and becomes dissolved in the blood; carbon dioxide diffuses across the membrane into the air.
