sprouts will grow from the potato tubule and grow more potatoes..... weird huh?
It gets softer.
When a potato slice/piece is placed in pure water, it gains mass and appears to be blown up. This is because the water is travelling into the potato because it has a lower concentration of water inside it.
If a potato slice is placed in tap water, the potato will absorb water through the process of osmosis. This causes the potato cells to swell and the slice to increase in size. The potato slice may also become softer due to the increased water content.
When a peeled potato is placed in distilled water, it will swell as a result of osmosis, as water moves into the potato cells where the solute concentration is higher. If some salt is added to the potato, it will cause the potato to lose water, leading to shrinkage, as the salt creates a higher solute concentration outside the potato cells, drawing water out.
~When you put salt in potato and then put it in the water cup, there is low water concentration in potato and more concentration in the cup of water. Due to this concentration gradient water moves from the cup into the potato by osmosis.
In osmosis, water will move from an area of higher concentration to an area of lower concentration. In potato A, if placed in a hypertonic solution (higher solute concentration), water will move out of the potato causing it to shrink (plasmolysis). In potato B, if placed in a hypotonic solution (lower solute concentration), water will move into the potato causing it to swell (turgor pressure).
No a potato will not get heavier if placed in salt water, and does it really matter if it does? Do not ask stupid questions. Keep it simple.
The hot saltwater will cause the potato cube to absorb the water due to osmosis, while the cold saltwater will cause the potato cube to release water. The difference in temperature affects the rate of osmosis – higher temperatures increase the rate, while colder temperatures decrease it.
Yes, because the distilled water has higher water potential as compared the the strip potato, so water will enter the potato by osmosis, through a partially permeable membrane, causing it to increase in size (:
When a potato is placed in water, the water concentration outside the potato cells is higher than inside. This creates a concentration gradient that drives water molecules into the potato cells through osmosis, causing the cells to swell and the potato to become turgid. The cell wall of the potato cells helps maintain the shape and prevents them from bursting.
Remember that the strip of potato is made of thousands of cells. When there is more salt outside the cells, water will leave. The strip will 'wilt' as the cell loses water and begins to shrivel up.
In a cylinder of potato tissue placed in distilled water, the direction of water movement will be from the external solution (distilled water) into the potato tissue due to osmosis. This is because the potato cells have a higher solute concentration compared to the external solution, resulting in water moving into the cells to equalize the concentration gradient.
