Adding 100% water (cell 90% water), the greater concentration is outside the cell, water will go into the cell b/c of the difference in concentration. When you don’t water it there is a greater concentration of water in the vacuole so it leaves and the vacuole gets smaller, the membrane shrinks and the plant starts to wilt

Types of Solutions

• Isotonic solutions have equal concentrations of solute

5% NaCl

95% H20

5% NaCl

95%H2O

• Hypertonic solutions have higher solute concentrations outside the cell

5% NaCl

95% H20

10% NaCl

90%H2O

• Hypotonic has less solute outside
• Water moves in
