Detailed explanation-1: -A semipermeable membrane, also termed a selectively permeable membrane, a partially permeable membrane or a differentially permeable membrane, is a membrane that will allow certain molecules or ions to pass through it by diffusion and occasionally specialized “facilitated diffusion". ( Wikipedia)
Detailed explanation-2: -A membrane that is selectively permeable, i.e. being permeable to only certain molecules and not to all molecules. An example of such membrane is the cell membrane wherein it allows passage of only certain types of molecules by diffusion and occasionally by facilitated diffusion.
Detailed explanation-3: -ˌse-ˌmī-, -mi-: partially but not freely or wholly permeable. specifically : permeable to some usually small molecules but not to other usually larger particles. a semipermeable membrane.
