Why did water diffuse out of a potato in a test tube of Na Cl?
Osmosis.
What happens to potato strip in dilute water?
This depends on the concentration of the salt solution. If the water potential of the salt solution is greater (less concentrated) than the cell sap of the potato cells, water would move into the potato cells, increasing the size of the potato strip. If the water potential of the salt solution is lower (more concentrated) than the cell sap of the potato cells, water would move out of the potato cells in the salt solution, decreasing the size of the potato strip.
What happens when the potato strip is in salt solution?
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.
Why do potato's shrink when you put them in water mixed with sugar?
The water in the cells diffuse out into solution via simple osmosis
Will the size of an unboiled strip of potato increase when placed in distilled water for 2 hours?
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 (:
What happen to a raw potato kept in salt water?
If it was placed in a salty solution the potato strip would shrink because the outer solution has a high salt concentration so the water in the potato strip would get out through osmosis and would try to balance the solution
What are effect of osmosis on potato strips?
This depends on the concentration of the salt solution. If the water potential of the salt solution is greater (less concentrated) than the cell sap of the potato cells, water would move into the potato cells, increasing the size of the potato strip. If the water potential of the salt solution is lower (more concentrated) than the cell sap of the potato cells, water would move out of the potato cells in the salt solution, decreasing the size of the potato strip.
Potato strip soaked in the 10 percent NaCl bendable?
The potato is bendable
Which salts does not diffuse in water?
Insoluble salts doesn't diffuse in water.
Does a larger surface area makes diffusion happen more quickly?
yes. Lets for example take a potato cube put in a jar of water. if the potato cube has a large surface area, then more of its surface will be exposed to water molecules, meaning that more can diffuse into it more quickly.
What causes oxygen from the water to diffuse into the blood?
the lungs causes oxygen from the water to diffuse into the blood
How does osmosis experiment take place with potato?
Beacause when you put the slice of potato in water osmosis takes place since concentration of water is lower then the concentration of the potato and water moves from ow concentration to high concentration so the water will move into the potato and the potato will become ridgid, But if you put salty water the salty water has a higher concentration then the potato so water will move out of the potato and the potato becomes soft.
