Osmosis in a Potato

Invasion into potatoes The main purpose of my experiment in this experiment was to investigate whether invasion occurred in potatoes and how it affected potatoes in different molar solutions of sugar and water did. Factor * Cell type * Various solutions * Solution concentration * Time cell in solution * Cell mass * Cell surface area * Solution temperature Predicted infiltration is a stronger solution through a partially permeable membrane from a weak solution It is the passage of water molecules to. .

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.

Invasion occurs between the potato and the solution. When potatoes are placed in 0% saline (distilled water), water molecules from the distilled water diffuse through the cell membrane of potato cells and enter the vacuole. This will cause the cells to inflate. So these potato tubers are hard when I touch it. Excess water molecules in the vacuoles enhance the quality of the potato tubers. When potato tubers are in 5% salt solution, they do not change as much as other potato tubers in other solutions. They are about the same length, but their mass is reduced the same as other potato tubers that lost water. This is because the salt content of potatoes is less than 5% and the salt water is about 4%. Because the cells are approximately isotonic with the solution and therefore do not need to spread out, so much penetration does not occur.

I predict there is penetration between potatoes and solutions. I think that the length and quality of potato tubers in distilled water will increase, but the quality and length of potato tubers in 100% saline will decrease. Somewhere between the two solutions, there is a salt concentration of potato tubers. There are several reasons why I made the above predictions. I learned about intrusions from previous experiments, and I know that it is a special case of diffusion. The water molecules pass through the partially permeable membrane. In this experiment, a part of the permeable membrane becomes a potato tubular cell membrane and the salt concentration of the potato tubers is examined. I know that water molecules move from high concentration to low concentration when infiltration occurs.
