Question
Osmosis Water moving by diffusion across a membrane is called osmosis. Remember, diffusion is the movement of molecules from a high concentration to a lower concentration, in order to reach equilibrium. In the image below, the diamonds represent water and the circles represent solutes. Water will move by osmosis from the side with a higher concentration of water to a side with a lower concentration of water. In other words, water will move by osmosis from the side with a lower concentration of solute to the side with a higher concentration of solute. Water is attracted to solutes. 2. Use the following diagram to answer the questions below. Start by filling in the blanks for the missing % concentrations for beakers B and C. 150ml 100 Beaker A 0% Sugar 100% Water a) What is the solute concentration of: O Beaker A? O Beaker B? 150ml 100 Beaker B % Sugar 90% Water b) What is the solvent concentration of Beaker C? 150ml 100 Beaker C 40% Sugar % Water When we think about solutions in human biology, we mostly think about the intracellular cytosol compared to extracellular solutions like plasma and interstitial fluid. (Remember, we are about 68% water.) To describe the relative amounts of solutes on either side of a membrane, we use the terms hypertonic, hypotonic and isotonic. If the solutions have equal concentrations of solute, we say that they are isotonic. If the concentration of solute is not equal, hypotonic describes the side with a lower concentration of solute and hypertonic describes the solution with a higher concentration of solute. Use the questions below to practice using these terms.
