the lettuce will begin to wilt do to the salt drying up the lettuce.
When a solution of salt or sugar is put on a mounted Rhoeo leaf, the process of osmosis occurs. Water moves from an area of higher concentration (inside the leaf) to an area of lower concentration (the solution outside the leaf), causing the leaf cells to shrink or swell depending on the concentration of the solution. This can disrupt the normal functioning of the leaf cells and lead to changes in their appearance.
The cells of lettuce leaf will be plasmolyzed due to exo osmosis.
Because the salt quickly causes dehydration.
it is to do with the water potential
The cell would lose water and the membrane would collapse.
Yes, but it is without any importance.
You get a salt solution.
When you deal with problems like this, you need to consider diffusion and osmosis. In this case, you would refer to diffusion, which is the movement of water across a membrane from high concentrations to low concentrations (to try to balance the concentrations). First consider what happens to the cells when you place the elodea leaf in the salt solution; the water in the cells tries to balance the high concentration of salt (sodium chloride) in the surrounding solution, so the water leaves the leaf, thus the cells shrink. Now when you put the elodea leaf into regular water again, there is a higher concentration of water in the surrounding environment compared to inside the leaf's cells, so in attempt to balance concentrations, water goes INTO the cells, thus the cells in the elodea leaf swell (expand).
Soaking lettuce in salt water can help remove dirt, bugs, and pesticides. The salt water will draw out impurities from the lettuce leaves, leaving them cleaner and potentially crisper. However, be cautious of oversoaking as it can lead to wilting.
Salt will crystalize out.
to get rid of bugs
The salt solution likely caused the cells of the Rhoeo discolor leaf to undergo plasmolysis, where water leaves the cells due to the higher concentration of salt outside the cell. This can lead to the cells shrinking and the leaf wilting or shrinking in size.
