Web1. Description of Diffusion and Osmosis. A water solution that contains nutrients, wastes, gases, salts and other substances surrounds cells. This is the external environment of a cell. The cell’s outer surface of the plasma membrane is in contact with this external environment, while the inner surface is in contact with the cytoplasm. Webdiffusion).

Indicators. are used to show the presence of certain kinds … WebWater is one molecule that easily crosses the cell membrane. The net diffusion of water through a selectively permeable membrane from the side of high water concentration to the side of low water concentration is termed osmosis. The higher the concentration of solute (dissolved particles), the lower the concentration of free water molecules. compare wordperfect vs word
