Osmosis observation of cells Statement of the problem: • What effects does pure water or 30% sucrose solutions have on a cell after its been soaked for a period of time in a beaker of solution? • This lab is to determine the effect that solution has on a cell. Observing the permeable membrane under different conditions: hypotonic, Isotonic and hypertonic. Results will vary by solution and mass. Hypothesis: • I predict that if the solution with in the cell, is the same as the solution outside the cell, therefore would be any change to the cell’s mass. This would be a result of an isotonic fluid witch has the same salute concentration as the cell. Materials: 1. Dialysis tubing 2. Scissors 3. String 4. Beakers 5. Pure water 6. 30% sucrose 7. Graduated cylinder 8. Mm rulers 9. Electronic balance Procedure: 1. First we started off by dividing into groups of 3, as each person is responsible for setting up a cell and a beaker. 2. Using your mm ruler to measure 10cm of dialysis tubing 3. Using scissors to cut the dialysis tubing and …show more content…
If the solution with in the cell is the same as the solution outside there is no change to the mass. My Isotonic cell stayed the same mass of 6.4. As for the other observations, Hypotonic witch was 30% sucrose solution inside the cell and distilled water in the outside, this cell went up on mass from 7.7g to 8.5g. in contract the hypertonic cell lost mass, this cell was made with distilled water inside the cell and 30% sucrose outside. This was a very fun and active lab assessment that helped me better understand the process of osmosis. Now, I can see how osmosis is used in our daily lives, from fruits to meats, medicine etc… its very interested in fruits because it’s made of 75% water, and this makes them user to spoil. To preserve fruits, it must be dehydrating the same way the use salt on meats. It’s not only about the water going in but coming out and its
