Different types of facility diffusion |
| Answer» The diffusion of the content over a cell membrane\xa0by means of transport proteins. It is a passive\xa0movement of molecules across the cell membrane from the region of higher concentration to the region of lower concentration by means of a carrier molecule.Dialysis:\xa0It is the diffusion of solutes across a selected permeable membrane. A selected permeable membrane is the one that allows specific content to pass through and other substances to pass slowly.Osmosis: The movement of water molecules from the region of higher water concentration to the region of lower water concentration through a semipermeable membrane.\xa0It is the diffusion of the solvent across a selected permeable membrane. Since water is solvent in every\xa0living being, biologists define osmosis as the diffusion of water across a selected permeable membrane.\xa0For example, Plants take water and mineral from roots with the help of osmosis. | |
