Osmosis

• The movement of water molecules from an area of higher water concentration to an area of lower water concentration through a semi-permeable membrane.
• ONLY water molecules move by Osmosis
• Rules= TYPE; DEFENITION (include water molecules); SPM; IN/OUT
• High to low
• Down a concentration gradient
• solution = water which has had something dissolved into it
• will occur until concentrations reach equilibrium (equal), but osmois still occurs (sides just stay equal)
• Net movement = total movement
• When reached equilibrium, there will be no net movement
• When there has been no overall gain/loss, equilibrium has been reached.
• higher temperature = more kinetic energy = quicker rate of osmosis
• The steeper the concentration gradient, the faster rate of osmosis
• Animal cells will burst if put in high water concentrations, however the cell wall in a plant cell stops them from bursting
