wilted lettuce are in a plasmolysed condition,when they are placed in a cold water or hypotonic solution then water enters the leaves by thye process of endosmosis and the leaves becomes deplasmolysed and they become crisp.

Would a reaction occur if a piece of metallic Sn were placed in distilled water with a piece of metallic zn?
No because there are no available ions to react with in distilled water.
What is the smallest piece of water called?
A molecule of H2O.
How much water is use to make one piece of paper?
One gallon of water
What is the smallest possible piece of water?
the smallest possible piece of water would be one water molecule. (one molecule of H2O), consisting of 2 Hydrogen atoms and 1 oxygen atom. Anything smaller, and it would lose the characteristics of water.
How does a piece of paper absorb water?
Because the paper is porous.
How do you freshen wilted lettuce?
In the ground spray over with water and if cut dip in water and put in the fridge.
What keeps lettuce from being wilted?
First of all...plant cells are bounded by a cell wall that can withstand the buildup water pressure. For example, lettuce is placed in a distilled water (pure water), they will be firm and crisp because water flows into the cells. As the water molecules flow into the cell, the plasma membrane begins to press against the cell wall. The bulidup of water pressure inside the cell is called turgor pressure, which causes the cell to become firm or turgid that lets it to be crisp.
Why lettuce leaf in contact with plain water is crispy while a lettuce leaf in contact within salad dressing containing salt and vinegar becomes wilted and limp?
it is to do with the water potential
What happens to restore lettuce to its original condition when you place wilted lettuce in cold water?
Not in ice water but cold water- it gets nice and crispy especially if you add a little bit of sugar
When a celery stick is nice crisp it has achieved a Wilted Spoiled Flaccid or Turgid?
It is turgid, meaning the cells are full of water so they are firm. This then supports the plant as a whole. The celery stick will then be nice and crisp.
What does tap water do to lettuce?
If you put the lettuce in fresh water there are more salts in the leaf than in the water, so the water will move back into the cells and make them rigid again, because the cells will swell. So if your lettuce in limp, laying it in water will make it crisp again.
How do you make wilted lettuce?
If the lettuce is still attached to the core, trim the core to reveal a fresh stem and then place the lettuce (core down) in a bowl of water with a sprinkle of sea salt added to the water. The lettuce will absorb the sea salt through the stem an be revived in a few hours. This works wonders in hot climate that cause lettuce to wilt quickly after harvest.
When put in water why does lettuce or spinach become firm and crisp?
Due to the process of osmosis, water moves through the selectively permeable membrane of the lettuce/spinach cells. Therefore, the lettuce/spinach becomes crisp.
If celery has gone limp how to make it crisp again?
put in water with some ice for a few minutes, and you can also do this with lettuce!
How does a wilted plant drink?
It takes in water by osmosis. This is why a wilted plant or even a wilted stalk of celery will become firm again if given water.
If vegetables become wilted they can often be made crisp again by soaking them in water. What process causes this change?
Osmosis is responsible for vegetables crisping up when soaked in water. The water diffuses into the cells and makes them turgid.
What is a wilted?
a wilted plant is a plant that has been drained out, that is, that it has no more moisture or water in them.
