put in water with some ice for a few minutes, and you can also do this with lettuce!
This process is known as osmosis. The water moves through the celery cells by osmosis, causing them to become turgid and the celery to become crisp and upright.
osmosis
Limp celery is generally safe to eat as long as it does not show signs of spoilage such as mold or a bad smell. However, the texture and taste may not be as desirable as fresh celery.
Freezing ruptures the cell walls, which gave the celery its structural firmness.
Plasmolysis
the cells in the celery lose water through evaporation, causing the celery to become dehydrated and limp. Celery has a high water content, so when it is exposed to air in the refrigerator, it can lose moisture quickly, leading to wilting.
Celery stays fresher in hypotonic water because it creates a lower concentration of solutes inside the celery cells compared to the surrounding water, allowing for water to flow into the cells through osmosis and keep the celery crisp. In hypertonic water, the higher concentration of solutes outside the celery cells would cause water to move out of the cells, leading to wilting.
When limp celery is placed in pure water, it undergoes a process called osmosis. Water moves from an area of higher concentration (the pure water) to an area of lower concentration (the cells of the celery, which have a higher solute concentration). This movement of water into the celery cells causes them to swell, restoring the celery's crispness and firmness. As a result, the celery becomes turgid as the cells fill with water.
First of all, you need to cut the celery into about six pieces or more.However you want. Top it off with whip cream or even better...sour cream. You can also top it of with salsa or cream cheese. You can also bake it if you like!:) I'm not sure if this is a celery crisp, but its good!
Because a hypertonic solution will take away the water from the plant, making the plant limp.
Osmosis could help revive the limp celery by allowing water to move into the plant cells through a semi-permeable membrane. If you place the celery in a bowl of water, the water will enter the cells, helping them regain turgor pressure and firmness. This process can rehydrate the celery, restoring its crispness and improving its texture.
Don't cut lettuce with a knife; tear it instead. Before you refrigerate it, put it into a plastic bag and twist to seal. It will stay crisp for quite a while. The same technique works for celery and other vegetables. There are special lettuce containers available but they're a waste of money; a simple plastic bag does the job just fine.
