What is a solution?A mixture of two or more substances.
A solution consists of a solute and a solvent.

A salt water solution…
• Is salt the solute or the solvent?– Solute
• Is water the solute or the solvent?– Solvent
• What does the solute do?– Gets dissolved
• What does the solvent do?– Does the dissolving

Cell Membrane consists of the lipid bilayer, carbohydrates, and proteins.
Water can pass right through lipid bilayer

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.
