What holds all plant cells rigid is osmotic pressure - which sucks water into a cell.
When the water is lost, so is the rigidity.
I need to know the answer to this for my homework. I heard it was 'plasmolysis' but we haven't learned about that yet and it is not one of my options. Hope it's one of yours, though!
plasmolysis
They are a different shape and have a dark premiter!
The Veins Will Turn Blue
Osmosis
nigel
As the water is poured into the glass, some oxygen dissolves in it. If the water doesn't move, the oxygen slowly diffuses out of it. If you were to pour in the water in a vacuum and then removed the vacuum and left the water stagnant, there would be no oxygen content decrease.

the celery take in the water
Yes a celery stalk is absorbent becase of the Vessel tissue, Xylem, and the Phloem which are the parts of the stem of the celery stalk where the tubes that carry the water and minirals.
By osmosis, water molecules in the vacuoles of the celery move into the salt water. Loss of pressure in the vacuoles causes the cells to collapse and the stalk to wilt.Concentrated water in the celery cells passes out to the saltwater where water is less concentrated.
The stringy cells are the xylem of the plant (tubes that the plant brings water through)
osmosis
The stalk of celery with leaves pulls up water faster, as water evaporates from the leaves, creating an area of low pressure, and the water moves up from an area of high pressure to an area of low pressure.
coz it's hidin
== == because the water makes the celery's cells go flaccid (stiff or erect) and that is why celery goes hard after being in water.
It is a myth that any food can "burn" calories. In fact, all foods and drinks (except for water) have caloris in them. A celery stalk has about 6 calories in it.
it has a larger surface area the celery stalks with out leaves & surface area is an enzyme that speeds up the transpiration in the Xylem tubes
