Abstract The reasoning behind this experiment was to be able to specify which molecules are capable of transporting in and out of the cell through the process of diffusion. Diffusion is the process where molecules move from a level of high concentration to low concentration and eventually stops once the equilibrium is reached. This study was able to demonstrate that glucose, starch, and silver nitrate were all existing at different amounts. Results began to show after around 40 minutes, but when we first started the experiment, no particles were present.

Introduction The technique in which molecules are able to move in and out of a cell is by the process of diffusion. Diffusion takes the molecules from a high level of concentration to a low level of concentration. This method will be tested by taking different solutions, such as glucose, starch, and sodium chloride, pouring them into a test tube, adding reagents to them, and analyzing which molecules are able transfer. Benedict’s reagent will be added to glucose, iodine to starch, and silver nitrate to sodium chloride. Glucose, starch, and sodium chloride will all be poured into the dialysis bag, which will be noted as the cell, and will eventually be examined along with the extracellular fluid, which is the fluid outside of the bag, or around the cell. The different directions that water is able to flow inside and outside of the cell includes hypertonic, isotonic, and hypotonic. Hypertonic solutions flow…
