Different types of facility diffusion

The diffusion of the content over a cell membrane by means of transport proteins. It is a passive movement 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: It 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. It is the diffusion of the solvent across a selected permeable membrane. Since water is solvent in every living being, biologists define osmosis as the diffusion of water across a selected permeable membrane. For example, Plants take water and mineral from roots with the help of osmosis.
