Lab Report Potato Osmosis

Introduction
When solutions have a lower concentration than the solution that is surrounding them, then that solution is known to be hypotonic. When solutions have a higher concentration than the solution that is surrounding them, then that solution is known to be hypertonic. When a solutions concentration has the same concentration as the solution that is surrounding it, then that solution is known to be isotonic. Osmosis is when molecules move from high concentrations to low concentrations with water. Diffusion is when molecules move from high concentrations to low concentrations. Water has to have a semi-permeable membrane, which means that only certain molecules are able to pass through due to size.
Materials and Methods
In step one of the lab, a dialysis tube had to be filled with 20-mL of potato starch solution and placed in a 500-mL beaker filled with 300-mL

The solution that have a molarity of 0, cause the object to be isotonic. If the temperature of the glucose solutions that had different molarities increased, the reaction of the potatoes weight would have happened faster. And vice versa, if the temperature of the glucose solutions that had different molarities decreased, then the reaction of the potatoes weight would have happened slower. If someone used animal cells instead of plant cells in this experiment, nothing would change because the only difference between plant cells and animal cells is the cytoplasm which has nothing to do with the experiment. A solution that is five percent glucose would be isotonic compared to red blood cells. If red blood cells are in a hypertonic solution, then the cells will shrivel up. If red blood cells are in a hypotonic solution, then the cells will swell. Which is why it is best for the solutions to be isotonic to the red blood
