Osmosis Osmosis is the movement of a solvent across a semipermeable membrane toward a higher concentration of solute. In biological systems, the solvent is typically water, but osmosis can occur in other liquids, supercritical liquids, and even gases.hen a cell is submerged in water, the water molecules pass through the cell membrane from an area of low solute concentration to high solute concentration. For example, if the cell is submerged in saltwater, water molecules move out of the cell.

- Diffusion is defined as the movement of molecules from an area of high concentration to an area of low concentration. The diffusion of water molecules through a selectively permeable membrane is known as OSMOSIS. Selectively permeable means that some molecules can move through a membrane while others cannot.iffusion is defined as the movement of molecules from an area of high concentration to an area of low concentration.

In and Out of Cells Very few particles travel the opposite way. The result is a concentration gradient with particles diffusing from an area of high concentration to an area of low concentration. Diffusion occurs in gases and with any substance in a solution.Therefore we can say that the definition of diffusion is as follows: Diffusion: The movement of particles from an area of high concentration to an area of low concentration until they spread out evenly. There are two important rules to remember.1  The larger the particles the slower the rate of diffusion.ery few particles travel the opposite way. The result is a concentration gradient with particles diffusing from an area of high concentration to an area of low concentration. Diffusion occurs in gases and with any substance in a solution.

Test Bank Of Essentials of Anatomy And Physiology 7th Edition by Martini Bartholomew 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.issolved 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.

- However, more water leaves a dilute solution (high water concentration) and passes into a more concentrated solution (low water concentration) than enters it. Although the water appears to move across the membrane in one direction, it is in fact moving in both directions but more one way than the other.

Osmosis will move water from a high concentration to a low concentration? Relevance. Rating Newest Oldest. Best Answer: osmosis moves water from high water concentration (i.e. where there is much water) to low water concentration. but notice that high water concentration refers to low solute concentration so ..... in terms of solute concentration ,....n simple terms, , a lower concentration of water means that it has a higher concentration of solute. So in two areas separated by a semipermeable membrane.water will move into the compartment having more solute because there is a lesser concentration of water. Source(s): Ph.D.

Osmosis and Diffusion a special case of diffusion where water diffuses through a selectively permeable membrane from a region of higher water potential to a region of lower water potential Permeable Membrane a membrane that allows for diffusion of certain solutes and water Active Transport uses energy from ATP to move substances throguh the cell membrane against a concentration gradient, from regions of low to higher concentrations

The Cell Membrane [Back to Microscopy and Cells] Osmosis [back to top] Osmosis is the diffusion of water across a membrane. It is in fact just normal lipid diffusion, but since water is so important and so abundant in cells (its concentration is about 50 M), the diffusion of water has its own name - osmosis.

Process of Osmosis vs. Diffusion Osmosis is the process of diffusion of water across a semipermeable membrane. Water molecules are free to pass across the cell membrane in both directions, either in or out, and thus osmosis regulates hydration, the influx of nutrients and the outflow of wastes, among other processes.

Osmosis When a cell is submerged in water, the water molecules pass through the cell membrane from an area of low solute concentration to high solute concentration. For example, if the cell is submerged in saltwater, water molecules move out of the cell. If a cell is submerged in freshwater, water molecules move into the cell.

What is the difference between diffusion and osmosis? Diffusion is a spontaneous movement of particles from an area of high concentration to an area of low concentration. 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.

Diffusion and Osmosis Facilitated Diffusion Osmosis - the diffusion of water (across a membrane) Water will move in the direction where there is a high concentration of solute (and hence a lower concentration of water. A simple rule to remember is: Salt is a solute, when it is concentrated inside or outside the cell, it will draw the water in its direction.
