Which process is responsible for the change in the mass of the potato slices?

Hear this out loudPausedoc. 4. If potato slices changed in length or turgidity, what process was responsible for this? -The process that was responsible for the change in length or turgidity is osmosis.

What process of movement caused the change you observed in the potatoes?

Hear this out loudPauseWater will move from an area of less salt to more salt (more water to less water), and so when the potato is placed in the saltwater, all the water that is inside the potato (yes, plants have a lot of water inside of them, that’s what gives a plant it’s structure) moves out by osmosis.

Why did the potato have a change in mass?

Hear this out loudPauseThe cell sap, therefore, loses water by osmosis and shrink. From the results, as the concentration of salts increases, the mass of potato reduces, therefore solution with 0.0 molarity of NaCl (aq) recorded an increase in mass while the ones with 1.0 molarity of NaCl (aq) recorded a great decrease in mass.

Is diffusion or osmosis responsible for changes in length of the potato slices?

Hear this out loudPauseIs diffusion or osmosis responsible for changes in length of the potato slices? Define both of these terms. The change in the length of the potatoes is due to osmosis. In the pieces of potato that were in saltwater solutions, all three lost length, while the potato in pure water got slightly bigger and heavier.

What is osmosis diagram?

Hear this out loudPauseOsmosis is the diffusion of water across a partially permeable membrane from a dilute solution (high concentration of water) to a concentrated solution (low concentration of water). In the diagram, the concentration of sugar is initially higher on the right side of the membrane.

What would your results be if the potato were placed in a dry area for several days before your experiment?

Hear this out loudPauseWhat would your results be if the potato were placed in a dry area for several days before your experiment? Cells would be dry, therefore higher gradient, water would flow into cells & Delta mass would be large for all solutions.

What does it mean if the potato did not change in mass?

Hear this out loudPauseIf there is no change in mass that means the potato and the solution have an isotonic sucrose concentration, in this case somewhere between . If there was not a change in mass, that means the potato and the solution are both isotonic, or have the same sucrose concentration.

Why is percentage change better than change in mass?

Hear this out loudPauseAnswer: The difference in mass does not deal with the proportional aspect of the solutions, making the results less accurate. The percent was calculated to give an exact difference, along with considering the quantities of solution.

How does the mass of a potato slice change when it is put?

Background: In this lab we will find out how water with different concentrations affects the mass of a potato slice when the slice is soaked in the water. In this lab the effects of osmosis will be seen. Potatoes cells are partially made up of water, this gives them the ability to perform osmosis.

How does the molarity of a salt solution affect potatoes?

Dependent: the change in potatoes depends on the molarity (concentration) of salt solution. As the salt concentration increases, there is a decrease in mass of potato tissue. Independent variable: time here is an independent variable; its change is not affected by either mass of potato tissue or the change in salt concentration.

Why does a potato cylinder increase in mass?

Active transport moves particles from low to higher concentration. For a potato cylinder placed in distilled water with a sucrose concentration of 0 mol dm−3 the following results were obtained. The increase in mass is the result of water being taken up by osmosis.

What happens when you put a potato slice in water?

In this lab we will put potato slices into water with different concentrations to see the effects of osmosis. Osmosis will occur because the concentration of water is different in Potatoes as in distilled water, tap water and water with…

How is the mass of a potato affected by osmosis?

It will have gained water by osmosis. A piece of potato has a mass of 2.5 g at the start and 2.0 g at the end. The minus sign shows that it has lost mass. It will have lost water by osmosis. Rachel carried out an experiment to investigate osmosis in potatoes.
