7. SOLUTE EGG WATER MEMBRANE Figure 1. Consider figure 1. Predict how water will move across the membrane. Water will move into the cell to where there is a higher solute concentration. Water will move out of the cell to where there is a lower solute concentration. Water will move into the cell to where there is a lower solute concentration. The cell and solution are in equilibrium, so water will move both directions equally. OO O

TONICITY DRAGTHE WORDS INTO THE BLANK SPACES BELOW TO ACCURATELY COMPLETE THE PARAGRAPH decreases Hypertonic increases key: Hypotonic solute particle • cell membrane cell wall solute in all solutions, the solvent is H20 solvent A В Solution B is to solution A. This is because solution B has a greater concentration of in it than does solution A. Solution C has no solutes dissolved in it, therefore it is to both Solutions A and B. As the relative concentration of solutes in two solutions increases, of necessity the relative concentration of water in the same two solutions Solution A has a lower concentration of than does Solution C; Solution A is also hypertonic to Sol tion C.
