The shrinking and expanding of the potato strips is due to osmosis. Potatoes are made of cells, and their cell walls act as semipermeable membranes. The 0 grams solution contains less salts and more water than the potato cells (which have more salts and less water). 9 янв. 2020 г.
What happened to the potato strip that was placed in a hypotonic solution?
If the concentration of the sucrose solution is low, which is a hypotonic concentration, the length of potato and apple strips size will increase and becomes turgid because the water moved out of the potato and the apple cells.
What happens to potato strips in sugar water?
Since potatoes already contain sugar, less water will diffuse out of the potato placed in sugar water. The slice placed in water will be rigid, since it will absorb water.
How does the size of potato strips when immersed in both water and salty water change over a period of 2 hours?
Interpretation. From the results, it is clear that as the concentration of salt solution increases, there is a larger decrease in the size of the potato.
What happened to the potato piece in distilled water and explain why?
Osmosis refers to the movement of water molecules across a membrane trying to achieve equilibrium. Because there are no salts in distilled water, there is a higher concentration of water molecules in the distilled water compared to inside the potato. Therefore water moves INTO the potato.
