This report was written to explain and present the results gathered in a precise and organized manner. This experiment was divided into two parts. The first part concentrated on the placing potato cylinders in different sucrose…show more content…
When this occurs most of the solute is now unable to diffuse to the other side the water molecules are now in the shells of the solute. The water is now not available for diffusion. In this case the water concentration is low. On the other side of the concentration gradient there is little or no diffusible solute. The water is “free”, thus allowing the water to move from areas of low solute concentration to an area of high solute concentration. Osmosis can affect blood cells based on the level of the solute. If a red blood cell were placed in a beaker of seawater, the red blood cell would shrink. This shrinking of the red blood cell happens because the seawater has more solute that the cytosol of the red blood cells. This situation causes the water to move out of the red blood cells. Due to the fact that the red blood cell shrunk this environment is considered hypertonic. When a red blood cell is dropped into a beaker of distilled water solution the red blood cell will burst. The reason the red blood cell exploded was because the cytosol has more solute than the distilled water and the distilled water move into red blood cell. This environment is called hypotonic. If a red blood cell is dropped into a beaker of the same solute concentration solution as the cytosol, the water will move in and out of the cell. This creates no net movement of
