#1-4 pg Osmosis 2. Semi-permeable or Selectively permeable 3. Hypertonic environment (salt water)-water would move out of the freshwater fish and cause dehydration Animal Plant Water will flow into both cells; Animal cell will eventually burst; plant cell has cell walls that will help keep the shape, allowing the cell to expand but not burst. Environment Cell Environment Cell #4

1. Euglena in Water Euglena- Hypertonic (more solute inside) Environment- Hypotonic (less solute, more water) Cell will increase in size Contractile Vacuole- pumps out excess water so the cell will not burst. Environment Euglena Water Solute Water

2. RBC.25% Salt placed in 2% Salt Solution RBC- Hypotonic (more water in cell) Salt Soln.- Hypertonic (more salt outside cell) Cell will decrease in size- water will leave the cell Water Salt Water Out Environment RBC

3. RBC Approx. 0.25% Salt placed in Distilled Water RBC % salt is hypertonic (more salt inside cell) Distilled Water- hypotonic (no salt in environment) Cell will increase in size Water will move from High to low concentration (into the cell) RBC Environment WaterSalt Water IN

4. Stalk of Celery in Salt Water Celery- Hypotonic (less salt inside celery cells) Salt water- hypotonic (more salt in Environment) Celery will decrease in size (water leaves the celery (high to low concentration) The water will leave the vacuole of the celery cell and leave the stalk limp.
