What is the goal of osmosis
moving water across the membrane to balance solute concentrations
What is an isotonic solution
solute concentrations are the same on both sides
What is a hypotonic solution
when the solution has a lower solute concentration
What is a hypertonic solution
when the solution has a higher solute concentration
Where will water go in an isotonic solution
water will exit/enter in equal amounts - plants will wilt, animal cells will thrive
Where will water go in a hypertonic solution
water will leave the cell causing membrane to shrink - plant will shrivel and pull away from cell wall, animal cells will die
Where will water go in a hypotonic solution
water will enter the cell causing membrane to fill with water - plants thrive, animal cells burst
