The Visking tubing is the selectively permeable membrane. Water moves by osmosis from the high water concentration (dilute solution) in the beaker into the low water concentration (concentrated ...

The net movement of water from a region of high water concentration to a region of low water concentration through a selectively permeable membrane. This means osmosis is a special case of ...

Increasingly though, researchers are looking to create ion-selective membranes by tweaking chemical ... “The change in selectivity and permeability is a sign that the channels interact with ...

A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific molecules from the external environment.
