Explanation:
Detailed explanation-1: -A membrane which allows certain substances to pass through it, but not others is called a selectively permeable membrane.
Detailed explanation-2: -Recall that the cell membrane is semipermeable. It does not allow everything to pass through. Some molecules can pass easily through your cell membranes, while others have more difficulty.
Detailed explanation-3: -They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly. Small polar molecules, such as water and ethanol, can also pass through membranes, but they do so more slowly.
