Osmosis Review
The cell membrane separates the internal cell solution from the exterior cell solution.

Cell Membrane consists of the lipid
bilayer, carbohydrates, and proteins.
Water can pass right through lipid
bilayerSlide3
What is a solution?
A mixture of two or more substances.
A solution consists of a
solute
and a
solvent
.Slide4
A salt water solution…
Is salt the solute or the solvent?SoluteIs water the solute or the solvent?SolventWhat does the solute do?Gets dissolved
What does the solvent do?Does the dissolvingSlide5

Cell Membrane consists of the lipid
bilayer, carbohydrates, and proteins.
Water can pass right through lipid
bilayerSlide8
The solute can’t fit through the membrane but the water can. The water moves through to make both sides’ concentrations at a state of
equilibrium.Slide9Slide10Slide11Slide12Slide13Slide14Slide15Slide16
