The net movement of water from a region of high water concentration to a region of low water concentration through a selectively permeable membrane. Osmosis requires facilitation by an energy-carrying molecule, such as ATP. Diffusion is when molecules or atoms move from an area of high concentration to an area of low concentration. The net movement of particles from a region of their higher concentration to a lower concentration down a concentration gradient, as a result of their random movement. For example in diffusion molecules will move from a region of high concentration to a region of low conc. The greater the concentration differences, the higher the rate of diffusion. Q. Example sentences with "diffusion movement", translation memory. UN-2 . The solution outside the cell will become (more/less) concentrated with the net movement of water. He further refutes the State party’s observation that ADR is a diffuse movement and that most of its members hold high positions. Structure of a cell- surface membrane. When diffusion has reached equilibrium, we say that the net movement of the molecules is 2. If we let random movement do it's thing, over time, the carriers will become evenly spread across the space through random motion alone. (ex. The diagram below represents the results of the net movement of a specific kind of molecule across a living cell membrane. chromatography. Osmosis is a type of diffusion that, in biology, is usually related to cells. Diffusion is the spreading of the particles of a gas, or of any substance in solution, resulting in a net movement from a region where they are of a higher concentration to a region with a lower concentration. Diffusion Diffusion is the net passive movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. It is the process of the net passive movement of particles from a higher concentration area to a lower concentration area in any mixture. Water movement. Definition of Diffusion. Diffusion is a result of the kinetic properties of particles of matter. Osmosis is the spontaneous net movement of water across a semipermeable membrane from a region of low solute concentration to a more concentrated solution, up a concentration gradient. These collisions cause the molecules to move in random directions. Erika. Osmosis is used for gases, such as oxygen and carbon dioxide. Gycerol. Diffusion is an important process, which is involved in the different life processes. Water is compelled to move inside to balance the concentration gradient. Net movement in diffusion occurs from areas of higher solute concentration to areas of lower solute concentration.B. Diffusion refers to the process of particles moving from an area of high concentration to one of low concentration. Diffusion definition is - the state of being spread out or transmitted especially by contact : the action of diffusing. Is hydrophillic. Structure. Diffusion is defined as the net movement of molecules from an area of greater concentration to an area of lesser concentration. Is hydrophobic. This movement accounts for the diffusion of molecules through whatever medium in which they are localized. 300 seconds . Diffusion is an important physical process and plays … Net movement means the overall direction of flow of a substance. Information and translations of diffusion pump in the most comprehensive dictionary definitions resource on the web. Chapter 5: Diffusion Diffusion: the movement of particles in a solid from an area of high concentration to an area of low concentration, resulting in the uniform distribution of the substance Diffusion is process which is NOT due to the action of a force, but a result of the random movements of atoms (statistical problem) 1. WikiMatrix. What is the best definition of diffusion? Diffusion refers to the net movement of atoms or molecules from regions of high concentration to regions of low concentration. SURVEY .
