Osmosis in Potato Cells

Invasion into Potato Cells In this survey we will investigate the infiltration amount into potato cells, the invasion of different concentrations of sugar solution and the quality of potatoes. We do this by adding a certain amount of potatoes to a solution containing steadily increasing sugar. Preliminary: We decided to conduct preliminary experiments to judge whether problems or obstacles exist before actual experiment.

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.

Since penetration is defined as the movement of water molecules through a portion of the permeable membrane from the high moisture concentration zone to the low moisture concentration zone, as the water concentration in the potato block decreases, the total mass and length also decreases Predict. (As the concentration of the sucrose solution increases, the change in the mass and length of the potato piece becomes more pronounced.) Because there is a stronger solution in the cell, by the end of the experiment it is predicted that the potato cube (0 M) in distilled water becomes the heaviest when infiltrating and water from the extracellular fluid enters the vacuoles and dilutes it It is. Therefore, the cells are filled with water and the result becomes unstable
