Water Potential of Potato Tuber Cells

Water Potential of Potato Tuber Cells: To Find the Water Potential of Potato Tuber Cells. Assumption: When a cell is placed in a solution containing moisture different from its interior, the cell increases or decreases moisture. If the solution concentration is the same, the quality will not change. Theoretical background: If the tissue sample is immersed in a solution of different water potential (water molecule concentration), the cell loosens or acquires moisture by permeation.

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.

Penetration is a special spread that occurs when I experiment between potato tubers and salt solutions. The water molecules pass through the partially permeable membrane from the high concentration zone to the low moisture concentration zone and the cell membrane of the potato functions as a partially permeable membrane. As you can see, the moisture potential of the solution is higher or lower than potato tubers, but potato tubers lose water molecules because of their high water potential if more than 4% salt is contained. When the salt content of the solution is less than 4%, potato tubers acquire water molecules because their water potential is lower than the solution. Salt and potato tubers in length and length increase to less than 4% in solution, so I can see this from my picture. It is higher than its mass and length.
