wilt and die
I think its just called plant dehydration because by the plant getting no water, it isn't able to preform osmosis, making the plants' cells shrink. The thing that keeps the plant upright is the cells absorbing water and swelling forcing the plant to stand. without water, the cells shrink and the plant loses its shape and starts to lean to the side.
There is no set percentage. When the plant loses more moisture through transpiration than is available to the roots the plant will eventually die.
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.
The Plant wilts and eventually dies. This is because the water has left the cell decreasing the turgor pressure water created by pushing the protoplast up against the cell wall. Eventually if water leaves the cell, the plant will wilt and die because it needs the water to carry out its processes like the light cycle.
Yes, plant cells contain plenty of water.
dehydration
Turgor would be lost when a plant loses water. Salt water can cause water to move out of plant cells and the plant would wilt.

Plant cells react in many ways. Because of its rigid structure, the plant cell will not just melt, it will just begin to cave in. For example... ------------------------------- I I I I I __________________I If this is the cell's structure, the top layer will cave in like this... ---\ /------- I \ / I I I I__________ You get my point!!!
dehydration
Yes, plant cells contain plenty of water.
The plant will begin to wilt as the cell loses structural integrity.
When a plant cell loses water it will undergo a condition called plasmolysis. This condition only happens in the extreme condition and rarely happens in the natural conditions.
Plant cells have a strong rigid cell wall on the outside of the cell membrane. This stops the cell bursting when it absorbs water by osmosis. The increase in pressure makes the cell rigid. This is useful as plants do not have a skeleton. Instead the leaves and shoots can be supported by the pressure of water in their cells. If plant cells lose too much water by osmosis they become less rigid and eventually the cell membrane shrinks away from the cell wall.
