the movement of water molecules only across a membrane. The water molecules will continue to diffuse across the membrane until equilibrium between concentrations is established. Osmosis takes place in both plant cells and animal cells. Animal cells do burst in pure water. The cytoplasm inside the cell is quite a concentrated solution of proteins and other large substances. Therefore osmosis will take place between the cell and the surrounding fluids via the partially permeable membrane (the cell membrane). The cell will soon burst because of the swelling from the increase in water. Plant cells do not burst in pure water, though, because they have a cell wall that is fully permeable so osmosis does not take place across it. It is bypassed and osmosis takes place between the cell membrane in the same way as an animal cell, but with the resistance of the strong cellulose...
