Osmosis is the movement of water molecules through a selectively-permeable membrane down a water potential gradient.
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?
osmosis, is the term that can be used for this scientific term
floating
When your fingers are in water for a long time, the outer layer of skin absorbs water and swells, causing the skin to wrinkle. This process is not due to osmosis, but rather a reaction of the skin to prolonged exposure to water.
That is a definition of abiogenesis, the scientific concept of life arising from non-living matter.
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.
No, a drawing of an atom is not a scientific definition. A scientific definition of an atom would describe it as the smallest unit of matter that retains the properties of an element.
