Importance of selectively permeable membrane
Witryna5 kwi 2024 · A semi-permeable membrane is a thin layer that allows certain substances to pass through it, while preventing the passage of other substances. It is mostly found in living organisms where it plays a crucial role in maintaining the balance of substances within cells. The word semi-permeable means that the membrane is selective in … WitrynaThis structure of cell membranes results in selective permeability. The phospholipids are tightly packed together in the lipid bilayer, and the membrane has a hydrophobic interior due to the lipid tails. A membrane that is selectively permeable allows only substances meeting specific criteria to pass through it unassisted.
