“Imagine a cell with a semi-permeable membrane is placed in a solution with a higher concentration of glucose than inside the cell. Describe, using the principles of osmosis, how water will move and explain why this movement occurs. A scientist observes that a cell placed in a certain solution swells up. Explain whether the solution is hypertonic, hypotonic, or isotonic relative to the cell, and describe how osmosis caused the cell to swell.”
