Investigating Osomotic Potential of Potato Cells

Examine the osmotic potential of potato cell equipment ========= This instrument puts potato chips into potato solution, removes the sliced ​​plug, cuts aphids / rods, distills water, dilutes the sucrose sucrose solution Use a boiling tube to show the infiltration process test tube Place the rack in the blade to cut it into the correct size and measure the scale of the chip with a cutting pad that cuts the tip above the measuring cylinder Method ==== == First collect all my equipment.

In the following experiments, we examine the glucose concentration in potato cell fluids before and after soaking the potato sample in the concentrated glucose solution. The stronger the glucose solution, the greater the potato piece weighs and I predict the potato will become heavier when placed in a more dilute glucose solution. This is due to penetration, that is, movement of water molecules from a high concentration region to a low concentration region. Because the cell membrane is water permeable, if the intracellular glucose concentration is higher than the concentration of the solution, the water molecules enter the solution through the cell wall and increase the weight of the potato.

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.

In this survey, we aimed to examine the concentration of potato cells. Potato slices can be placed in different concentrations of sugar and concentrations that are isotonic with potato cell juice can be found. With such a solution, a piece of potato does not increase or decrease the weight. My hypothesis is that the isotonic point lies between 80 and 120 g / l. This is a preliminary experiment to show where the isotonic point is, so I will predict this. I think 50 g / l potato chips will swell and increase weight. The tip concentration is lower than water and absorbs water. As a result, water molecules are the same as inside the chip. Potato chips of 90 g / l have a high concentration of sugar on the outside of the chips, so they lose sagging weight. Since the chip releases moisture, the moisture concentration is equal to the moisture concentration inside the chip.
