Osmosis Worksheet
Below are animal cells placed in beakers of various concentrations. Use the first picture as an example.
  1. Select the direction that water moves (into the cell or into the solution)
  2. Fill in any missing percentages (water or solute)
  3. Identify the type of solution (isotonic, hypertonic, or hypotonic)
EXAMPLE:

The total amout of water and solute together in a cell will add up to 100%.

The total amount of water and solute in the solution in the beaker will add up to 100%.

In this example the solute concentration in the cell is 79% (math. 21% + x % =100% ).

The percentage of water in the solution is 32%

Water would move into the cell because water is at a higher concentration out of the cell and water alsways moves from high concentration to low concentration.

The solution is HYPOTONIC because it has a higher concentration of water than the cell.
