Partially permeable membrane examples
Web8 Jun 2024 · Visking tubing is an artificial partially permeable membrane. It has microscopic holes in its membrane that only allow small molecules through (like water) and not larger molecules (like sugar sucrose); in other words, it is permeable to small molecules like water but not larger molecules – this is why it is known as ‘partially’ permeable. WebAnswer (1 of 4): In biology, a simple example of a permeable membrane is a cell wall. In both plant and animal cells, the cell wall is a permeable membrane that allows the passage of particular substances while preventing others. This is known as semi-permeability. Semi-permeability is found in p...
