|Water move from higher concentration towards lower concentration across the plasma membrane.|
|Somtirthaa said: (Feb 3, 2012)|
|Its not just water. To be general, its the 'solvent' molecules. If the solvent is water, then we shall talk of water molecules !|

|Plasma membrane is a semi permeable membrane.|
|Huma said: (May 11, 2014)|
|Why flow of solution is not possible through semi-permeable membrane?|
|Roy M said: (Jun 28, 2014)|
|Osmosis is the movement of diffusion through polythene to form chloroplast.|
|Angellina said: (Oct 10, 2014)|
|Osmosis involves semi permeable membrane. Then why is the answer like this?|
|Shiv said: (Oct 12, 2014)|
|Please read the below statement carefully.
"Osmosis is the spontaneous net movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. ".
Movement of solvent not solution.
|Rachana said: (Nov 6, 2014)|
|Osmosis involves selective permeable membrane b/c semi permeable membrane allows the movement of other molecules in solution through the layers of membrane whereas selective permeable membrane allows movements of only specific molecules through the layers of membrane in any cell.|
|Vivek said: (Apr 20, 2015)|
|Only solvent passes in osmosis not entire solution.|
|Ravi said: (Jun 28, 2015)|
|Only solvent can pass through semi-permeable membrane, solute cannot. So the flow of solution which is combination of both solute and solvent, is not possible through semi permeable membrane.|
|Manjunatha said: (Oct 12, 2015)|
|The movement of solution, solvent and solute are pass the semipermeable membrane. The osmosis can be explained on the basis of solute and solvent as well.
It is a movement of solute molecule from lower concentration to higher concentration through semipermeable membrane. OR It is a movement of solvent molecule from Higher concentration to lower concentration through semipermeable membrane.
|Pragathi Bansal said: (Apr 6, 2016)|
|It is not the solution that moves.
It is the solvent particles that moves in osmosis.
|Ria said: (Apr 27, 2016)|
|Osmosis is a type of 'specialised diffusion' which involves the passage of solvent from a region of high solvent concentration to a region of low solvent concentration across the semi-permeable membrane.|
|Eric Goodluck O said: (Nov 1, 2016)|
|Osmosis is the movement of solvent molecules from a lower to a higher reg of concentration through a semi-permeable membrane.|
|Ritu said: (Mar 25, 2017)|
|Osmosis is one kind of specialized diffusion, that involves the movement of solvent molecules from higher concentration to lower concentration by the help of a semipermeable membrane.|
|Shivathmi Gowda said: (Apr 29, 2017)|
|Actually, osmosis is a region of higher water potential to the region of lower water potential.|
|Ini said: (Jul 29, 2017)|
|When we talk about osmosis, water molecules passes through a semi-permeable membrane while solutions can pass through a selective permeable membrane.|

|This was a very helpful question. Thanks all.|
