What is a Semipermeable Membrane? Discussion Comments By scifreak — On Apr 20, 2011 Since cells are selectively permeable, does that mean they can be selective and allow prescribed medications into the blood stream? For example, I take high blood pressure medicine. Is the reason it works is...
A semipermeable membrane, like the membrane of a cell wall or a bladder, is selective about what it allows to pass through, and what it prevents from passing. These membranes in general pass water very easily because of its small molecular size; but also prevent many other contaminants from ...

Semipermeable cell walls or apoplastic "membranes" have been hypothesized to be present in various plant tissues. Although often associated with suberized or lignified walls, the wall component that confers osmotic semipermeability is not known. In muskmelon ( Cucumis melo L.) seeds, a thin, ...

All animal cells have a plasma membrane. This is a barrier that surrounds the cell and holds it together. It controls what goes in and out of the cell. The cell membrane is made of proteins and lipids (fatty substances). It is ‘semipermeable’, which means that some chemicals can get ...
