Witryna24 wrz 2024 · Selective permeability is an essential feature of the plasma membrane. Without it, the cell would be unable to control the molecules entering and leaving the cell. This would disrupt the cell’s normal functioning, leading to a malfunctioning cell and eventually cell death. 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.
