Using the Scientific Method. Investigating Osmosis in Potato Cells.

Keynote lecture: "Using scientific methods - Investigation of invasion into potato cells" - Presentation:

Permeation is a special diffusion of water from a high moisture concentration through a selectively permeable membrane to a low moisture concentration.

Hypotonic solution: Because extracellular water is more than inside, water enters the cell by infiltration. It swells the cells and swells them with hypertonic solution: As the water inside the cells is more than the outside, water moves out of the cells by infiltration. This makes the cells softer or more relaxing.

The teacher enters the result into the form and asks the individual to record the result of each person and obtain a series of average results.

The potato sample in beaker A was covered with 50 ml of water and the potato sample in beaker B was covered with 50 ml hypertonic solution. After 30 minutes, remove the sample from the beaker, dry it with a new paper towel, and remeasure the quality of each potato.

11 RESULTS ANALYSIS The finished results table data was used to create a bar chart showing the quality of potato cylinders in both 0 and 30 minutes solution.

13 Conclusion The purpose of this scientific study is to investigate what happens when potato samples are placed in hypertonic solution.

The purpose of the investigation was to investigate the osmotic effect of the potato and find its sucrose concentration. For permeation, it occurs in the cell membrane of potatoes. The cells in the potato are similar to the plant cells described earlier from the point of penetration. Therefore, I predict that if water is put in purified water, the water will spread out in potatoes. In addition, putting water in a very thick sucrose solution, it is expected that the water diffuses out of the potatoes. This is because potatoes are a type of root crop that can 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, I will explain the penetration. 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 proteins to pass through. A high concentration of water is a very dilute solution such as sucrose or pure water. In any case, there is a lot of water. That is, it is high concentration water. The low moisture concentration range is opposite to the above.

Experimental purpose to study plant cell permeation Objective The purpose of this experiment was to investigate the movement of plant cells that passed through the semipermeable membrane in different concentrations of sucrose solution and exited into the water. Experiments and plant cells used were potato and radish tissues used as potato chips, as results and changes were easily recorded and thus recorded. Due to the different permeability of plant cell membranes, the expected results of radish and potato chips are different under the same conditions; this is one reason why we have two plant cells instead of one. Another reason is that we can compare the results of two plant cells and compare similarities between specific results.
