Detailed explanation-1: -/ˌsem.iˈpɝː.mi.ə.bəl/ Something, for example a cell membrane, that is semipermeable allows some liquids and gases to pass through it, but not others. Holes, hollows and dips.

Detailed explanation-2: -ˌse-ˌmī-, -mi-: partially but not freely or wholly permeable. specifically : permeable to some usually small molecules but not to other usually larger particles.

Detailed explanation-3: -Cell membranes serve as barriers and gatekeepers. 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.

Detailed explanation-4: -A semipermeable membrane allows only solvent molecules to pass through while leaving behind solute molecules. Such type of diffusion of water through a semi-permeable membrane is called osmosis.

Detailed explanation-5: -Membranes that are semipermeable are permeable to some materials. The cell membrane is semipermeable to small, uncharged molecules like oxygen and carbon dioxide. It is selectively permeable to molecules the cell needs, such as glucose, amino acids, and more.
