All cells in our body exhibit the property of selective permeability. Selective permeable membrane allows certain sized particles to enter the cytoplasm while restricting large sized macromolecules. Ions can diffuse through the plasma membrane via various ion pumps.

Is a cell phone a pure substance or mixture?
Its a mixture because it has different types of mechanical electronics
Is Mineral water pure substance or mixture?
No. A pure substance describes one that contains only one type of element/molecule. Mineral water is a mixture, since it contains many different types of minerals, next to water, and can therefore not be called a "pure" substance.
Is cell wall is a permeable membrane?
it is not selective permeable. - Cell membranes are selective permeable. Cell walls are fully permeable - which means that it allows all substances/molecules to pass in and out of the cell. It is located outside of the membrane.

What does it mean to be selectively permeable semi-permeable?
DefinitionnounA membrane that is selectively permeable, i.e. being permeable to only certain molecules and not to all molecules.SupplementAn 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.by~paula razon (facebook)!!!
Type of tubing that is semi-permeable?

What are all the passive transport in a cell?
There are two types of passive transport in a cell:Diffusion - the substance moves down a concentration gradient across a partialy permeable membrane. This requires no energy.Osmosis - WATER moves down a water potential across a partially permeable membrane. This requites no energy.
