What else can I help you with?
What is the movement of molecules from areas of higher concentration to lower concentration until equilibrium is met?
The movement of particles from an area of high concentration through a semi-permeable membrane to an area of low concentraton is the process of diffusion. I'm sorry but I do not think that answer is good enough. It is a form of diffusion, where only small particles, small enough to pass through the membrane can get through. When I was in school the statement above was the definition of osmosis, the whole point being it was diffusion through a semi-permeable membrane, selecting for only small enough particles. It seems some time between 1992 and 2003 the definition was changed to the movement of water, and not particles and now in 2010 the definition is the movement of solvents. I would like to know how and why the definition osmosis was changed, why and what is the justification? I would also like to know why the original meaning of osmosis, which made perfect sense, has been changed to "it's the definition of diffusion and not osmosis any more", when in fact it isn't a clear enough word to describe the process? Surely the new definition of osmosis is also diffusion?
What is the scientific definition of osmosis?
Osmosis is the movement of water molecules across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration, in order to equalize the concentration of solute on both sides of the membrane.
Passive transport of water is known as?
floating
What process is the diffusion of water through a selectively permeable membrane?
The process of water passing through a selectively permeable membrane is called osmosis. Water will move from an area of higher concentration to an area of lower concentration in order to equalize the solute concentrations on both sides of the membrane.
What is the definition of osmosis?
The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis. Passive transport is the movement of a substance across a cell membrane with its concentration gradient (from high to low concentration) and it uses no energy. Osmosis is a special term used when water is the substance being moved.
By definition what is the only substance that carries out osmosis?
The definition of osmosis does not restrict this phenomenon to any single substance. I don't know where you would get that idea. In practice, most of the situations involving osmosis, that are of interest to us, take place in an aqueous medium. But osmosis can occur in other media.
What is the relationship between osmosis and diffusion by definition what is the only substance that can carry out osmosis?
Osmosis is a specific type of diffusion that involves the movement of water across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration. Water is the only substance that carries out osmosis due to its ability to move freely through the membrane.
Do osmosis has a high or low concentration?
As per Definition of osmosis: "Osmosis is the passage of water from the region of high water concentration through a semi permeable membrane to a region of low water concentration". Thus, Osmosis do have an area of high and low concentration of water solutions.
What is the relationship between osmosis and turgor pressure?
Water enters into plants by Osmosis and water causes turgor pressure Tugor definition= the state of turgidity and resulting rigidity of cells (or tissues), typically due to the absorption of fluid.
Best definition of osmosis?
Osmosis is the movement of solvent molecules from an area of lower solute concentration to an area of higher solute concentration through a semi-permeable membrane, in order to equalize the concentration on both sides of the membrane.

Osmosis is a diffusion process that moves through the membrane from higher to lower concentration. molecules salt water nutrients?
Switch the word "solvent" to "water" and you have the best definition possible.
Passive transport of water is known as?
floating
Does osmosis require a carrier?
NO. Osmosis( by definition) is the DIFFUSION of water from a high concentration gradient to a low concentration gradient across a semipermeable membrane. As diffusion is a form of passive transport, it doesnt require a carrier
What process is the diffusion of water through a selectively permeable membrane?
The process of water passing through a selectively permeable membrane is called osmosis. Water will move from an area of higher concentration to an area of lower concentration in order to equalize the solute concentrations on both sides of the membrane.
What is the complete definition of diffusion osmosis?
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Osmosis is the movement of solvent molecules (usually water) across a selectively permeable membrane from a dilute solution to a more concentrated solution. Together, diffusion and osmosis are vital processes in maintaining the balance of substances within cells and across cell membranes.
