Osmosisis the diffusion of water through aselectively permeable membrane.<strong>Study</strong> the beakers at the right. Thearrows between beakers tell youwhat process is occurring.1. In the beakers on the right,draw the result of the describedprocess. Draw changes in waterlevels. Draw changes in the numberof solute particles. Remember todraw on both sides of themembrane.2. Look at the top left beaker. Whatwould happen if the membrane didnot allow water or solute particlesto pass through it?watersoluteparticlesmembraneDiffusionofSoluteParticlesnumber of solute particlesshould be the same on bothsides of the membraneOsmosisnumber of solute particles doesnot change, just level of watersolute particle movementwater movementThe solutions would stay the same. Neither water nor solute particles would movethrough the membrane.Lesson <strong>7.3</strong> • Workbook B • Copyright © by Pearson Education, Inc., or its affiliates. All Rights Reserved.102
