When solutes move across a semipermeable barrier from areas of high concentration to low concentration:   it requires energy input. it requires no net energy input. it causes the water to go up. the total solute concentration increases.

Type of Solutes Non-permeable Permeable Solution A 300 0 Solution B 295 20 Solution C 270 30 A cell with an internal osmolarity of 295 mOsm/L (non-permeable solutes) is placed in solution A. Solution A has an effective osmolarity that is ____________ compared to the cell; after water movement has reached a steady state, the cell volume will be ___________. A) hypertonic; decreased B) hypotonic; increased C) isotonic; decreased D) hypertonic; increased A cell with an internal osmolarity of 295 mOsm/L (non-permeable solutes) is placed in solution B. Solution B has an effective osmolarity that is ____________ compared to the cell; after water movement has reached a steady state, the cell volume will be ___________. A) hypotonic; decreased B) hypertonic; decreased C) hypotonic; increased D) isotonic; unchanged A cell with an internal osmolarity of 295 mOsm/L (non-permeable solutes) is placed in solution C. Solution C has an effective osmolarity that is ____________ compared…

Do you expect water to continue to flow across the semipermeable membrane after osmotic equilibrium is reached? Why or why not?

Mark the flow of water with an arrow for cells that have been placed in solutions of differing tonicity. Indicate what will happen to a plant and animal cell under each of these conditions. Direction of osmosis Plant cell Animal cell shape shape minor swelling The solute concentration outside the cell is isotonic (or equal) to the inside of the cell. No change swelling and lysis plasmolysis crenation Reset Zoom (a) Outside isotonic The solute concentration outside the cell is hypertonic to the inside of the cell. (b) Outside hypertonic The solute concentration outside the cell is hypotonic to the inside of the cell. (c) Outside hypotonic Oo Solute Cytosol ©2018 McGraw-Hill Education. Check m
