Activity 3d - Osmosis in plant cells 1. Fill in the table below to indicate what happened to the elodea cells in each of the following solutions. Solution Hypertonic Isotonic Hypotonic Distilled water Activity 3e Osmosis in red blood cells 1. Summarize the results of the experiment in the table below. First, indicate what the tonicity (hypertonic, hypotonic or isotonic) of the solution is and then describe the appearance of the red blood cells. Solution 10% NaCl Will the cell membrane swell or shrivel? .9% NaCl What happens to the chloroplasts in the hypotonic solution? Why do you think that happens? Tonicity of the Solution Describe the appearance of the red blood cells 1. Saltwater fish live in an environment that is saltier than the inside of their cells. Explain which way water would move relative to the cells of their bodies (i.e. would water move in or out?).

Solutions Matching - Identify the solution type described in the questions or statements below. determine if hypotonic hypertonic or isotonic      A cell is bathed in solution X.  The cell quickly shrivels.  What term describes solution X (when compared with the cell's fluid)?     A saline (salt) solution is to injected into a patient.  The salt/water ratio should be adjusted so that the saline solution is ____ to the patients cells.     Solution Q has a higher water content that solution Z.  Therefore solution Q is ___ to solution Z     Solution which may cause a cell to lyse.     When a cell is placed in this type of solution, there will be equal amounts of water moving in and out of the cell at equal rates.     Solution with a higher solute concentration (less water)     The concentration of the solute in the solution is lower than the concentration inside the cell.     When a cell is placed in this solution, water will enter…
