Question

what would happen if a plant cell did not have a cell wall

Answer 1

 The cell wall supports and protects the plant cell.Take osmosis for example,only plants are exposed to fresh water, animal cells and bacteria are rarely,usually never, exposed to fresh water. since the solution or cytoplasm inside the cell membrane is hypotonic (less concentrated with water) than the fresh water,osmotic pressure will cause water to diffuse across the cell membrane into the cell (osmosis), trying to equalize the concentration, causing the cell to inflate. the cell wall protects this cell from bursting. so if there was no cell wall, plants could not intake fresh water.
