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?

High to low: For water- osmosis
High to low: For substances: Diffusion
Low to high: Active transport.

Diffusion is the movement of a substance?
from an area of high concentration to an area of lower concentration.
Movement of molecules from high high to low concentration?
Movement of molecules 4m higher to lower concentration is called osmosis
What is the natural tendency of molecules to spread from an area high concentration to an area of low concentration?
Diffusion is the movement of molecules from a high concentration to a low concentration without using ATP (energy). A related term: Osmosis is the movement of water molecules from a high concentration to a low concentration without using ATP (energy). In contrast, active transport is the movement of molecules from a low concentration to a high concentration but DOES use ATP (energy).
What particle movement from an area of higher concentration to an area of lower concentration?
they move from an area of high concentration to low concentration in an effort to create equilibrium.
Movement of molecules from higher concentrated areas lower contrated areas?
This process is called diffusion. Diffusion moves things from areas of high concentration to areas of lower concentration in order to create a concentrated equilibrium between the two areas.
Diffusion is the movement of a substance?
from an area of high concentration to an area of lower concentration.
How are diffusion and osmosis process the same?
Both involve passive transport: The movement of molecules from a region of higher concentration to a region of lower concentration in order to reach a state of equilibrium.
Movement of molecules from high high to low concentration?
Movement of molecules 4m higher to lower concentration is called osmosis
When a solution as a greater concentration particles?
Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. This is due to the random movement of the molecules.
What process is illustrated by the arrows labeled a in figure6-1?
The process illustrated by the arrows labeled "a" is diffusion. This is the movement of molecules from an area of higher concentration to an area of lower concentration, driven by the natural tendency of molecules to spread out and reach equilibrium.
What is diffusion and how does it relate to the movement of material into and out of the cell?
diffusion is the kinetic movement of molecules from higher concentration to lower concentration.
What do molecules move along in diffusion?
Molecules move a from regions where they are in higher concentrations to regions where they are in lower concentrations. Random
What movement of gas molecules from a region of higher concentration to a region of lower concentration?
osmosis is the passive movement of a substance from a place where its concentration is higher, to another where its concentration is lower. This applies to gases, I guess
Which terms refers to the movement of molecules from an area of higher concentration an area of lower concentration?
Diffusion, a form of passive transport, is the movement of molecules from an area of greater concentration to an area of lower concentration. Osmosis is a special case involvement the movement of water from an area of higher concentration of water molecules to an area of lower concentration of water molecules. It takes place in all three states of matter-Solids, liquids and gases.
What is the term for the movement of molecules from an area of lower concentration to an area of higher concentration?
If it is the movement of molecules then it is diffusion. If it the movement of water then it is osmosis
