Osmosis Essay title: Osmosis Osmosis Osmosis is just a special case of diffusion – where water diffuses through a membrane which has different concentrations on either side. Permeable means “allows anything to pass through”. Membranes in cells allow small molecules (water) to pass through, but prevent bigger ones from passing. This is called “selectively permeable”..
The Cell Membrane in CellsEssay title: The Cell Membrane in CellsThis can be seen in living cells. The cell membrane in cells is semi-permeable and the vacuole contains a sugar/salt solution. So when a cell is placed in distilled water (high water concentration) water will move across the semi-permeable membrane into the cell (lower water.

Introduction: Osmosis is the movement of water molecules across a partially permeable membrane form a region of high water concentration to a region of low water.
