If a cell has no cell wall it dies and can't perform all the necessary functions of cell life.

only plant cells have cell walls. animal cells have no cell walls but rather a cell membrane that is selectively permeable to water. a unique feature the plant cell's cell wall, is that when the water concentration outside the cell become large, water rushes into the cell the try to equalize with the outside water. The makes the cell swell up like a balloon. Now, in an animal cell, with no cell wall, this excess water would cause the cell to grow so large that the cell membrane could not contain it and the cell would burst. WITH a cell wall, like in a plant cell, the cell will grow, but will not burst, because the cell wall is rigid, and maintains the the pressure from the swelling cell. This is called a "turgid" cell and is how plant cells would prefer to be because it means their water needs are being met.

only plants have cell walls so when the water diffuses in side the cells.. the cell wall can take the turgor pressure created. If the wall wasnt there the cells of the plant would explode( thats called something like cytolysis)

i kind of forgot this topic and i'm not sure this'll help...
plant cells have the cell walls right? so, technically, the cell wall is needed as a form of protection and to keep the cell, well, whole. if there isn't a cell wall, then the osmotic pressure would cause the cell to burst.
that's what i remember

cell wall is present in plant cells. without it, a plant cell goes on absorbing water and it bursts
plant cells become turgid when they r watered but cell wall prevents bursting

without cell wall, the cells would not have its shape and it could easily burst during osmosis. Also, the tension or pressure exerted against cell wall help transportation of nutrients in plants (xylem and phloem) (capillary action)...

the plasma stuff inside will spread because the wall holds it in. sorry i havent done bio for a while
