Investigating Osmosis in Potatoes

Study the infiltration of potatoes: Study the penetration by selectively permeable membranes (in this case potatoes). Introduction: Permeation is the movement of water through a semipermeable membrane. Water flows from the high concentration zone to the low concentration zone until the water concentrations of the two concentrations are equal. Many cell membranes appear like semipermeable membranes, and penetration is an important part of fluid movement in the body. For example, it is the transport of water from the soil to the root of the plant.

What I change will be the concentration of the solution that will help you study the penetration of potato tissue, in the investigation of the independent variables (what you change) and the factors that affect penetration. When potatoes were placed in sugar solution placed at different molarity (strength), different sugar concentrations were changed to observe potato results. Dependent variable (what you measure) In this permeation experiment it is measured the change in mass and length of potatoes in different molar concentrations of sugar solution. Record the mass in grams and change the length using a ruler.

The purpose of the investigation was to investigate the osmotic effect of the potato and to find its sucrose concentration. Regarding infiltration, it occurs in the cell membrane of potatoes. The cells in the potato are similar to the plant cells described earlier from the perspective of penetration. Therefore, I predict that if water is put in purified water, water will spread out in the potatoes. Furthermore, if water is added to the concentrated sucrose solution, I think that the water diffuses outside the potato. This is because potatoes are root crops, which absorb moisture on the ground, potato cells need to contain a large amount of moisture.

The purpose of this experiment was to investigate water transfer to and from plant cells. Cells selected for research are taken from potato tubers. First, let me explain about permeability. Permeation is the passage of water from the high moisture concentration zone through the semipermeable membrane to the low moisture concentration zone. Three important things are included in this definition. A semipermeable membrane is a layer of very thin material that blocks something while hindering others. The cell membrane is semipermeable. They allow small molecules such as oxygen, water, and amino acids to pass through but do not allow larger molecules such as sucrose, starch, and protein to pass through. The area of ​​high concentration water is a very dilute solution such as sucrose or pure water. In each case there is a lot of water: high concentration water. The low moisture concentration range is opposite to the above.
