They have a cell wall, a fully permeable structure composed of closely woven cellulose fibres, which strengthens the cell and prevents lysis (the breaking down of a cell).
the cell wall prevents expansion/bursting (keeps cell together) and uptake of too much water freely passing through membrane. <this could be right
No, because plants cells have cell walls, they gain turgor pressure, until eventually it stops osmosis and no more water is gained, so the cell doesn't rupture.
Plant cell sizes and shapes are rather rigid due to their cell wall which keeps it from expanding to the point of bursting.
paramecium, since it lives in fresh water, it has a contractile vacuole so that it doesn't gain too much water and burst
When a plant cell is full of water. It will get ready to burst. But if it tries to burst it will not. Because of something that a plant cell has. It is a Cell Wall.
Atleast in Phylum Ciliophora - unicellular, heterotrophic, protist, 'animal-like,' surface covered by cilia - it has a contractive vacuole that helps. The fresh water goes into the cell and the contractile vacuole squeezes the water out again, otherwise, it would explode. I am not a teacher or an expert on this, but I do have an exam on all of the Phylums of Kindom Protista in my Biodiversity class tomorrow, so I'm pretty well researched on this.
yes
Plant cells are selected to demonstrate plasmolysis rather than animal cells. This because thy have the ability to absorb water through endosmosis unlike animal cells which would burst.

because Fresh water enters easly in the plant cells by endo osmosis. Thus, it causes better growth to the plant.
The plant is most likely to die because the salt water already killed the root cells. It also depends on the concentraition of the plant. some plants are very sensitive when fresh water is placed in ONLY salt water plants

The plant's cell wall is tough enough to withstand the pressure that animal cells cannot
Jellyfishes are evolved to live in saltwater, and their cells have mechanisms for absorbing water and excreting salts. However, in freshwater this ability works against them, causing them to swell up with water, and their cells burst.
Water would rush in, causing the cells to burst.
It would die.
Because there is more salt in the plant cells, when they are placed in pure water (with no salt), water will move into the cells in an effort to balance the concentration inside the cell and out the cell. The plant cells will become enlarged with water and may burst. This is a way to make wilted celery to become like it did when it was bought.

Unlike animal cells, plant cells are unable to control the compostiton of fluid around their cell. Plant cells are normally permanetly bathed in almost pure water, which is constantly absorbed from the plants roots. Water entering a plant cell by osmosis causes the protoplast to swell and press on the cell wall. Because the cell wall is capable of only very limited expansion, a pressure builds up on it that resists the entry of further water. However animal cells do not have this ability and let constant water in, causing it to burst.
NO.
