Soluble Permeability Permeable Molecules Water Structures Cell Membrane

Front How does the structures in the cell membrane determines its permeability properties? (6mks)
Back
It has a phospholipid bi layer 

Its only permeable to lipid soluble molecules / oxygen

It is impermeable to water soluble molecules / ions / polar

Contains aquaporins (proteins) that provide permeability to water 

It has transport proteins (channel, carrier) that allows water soluble to pass through 

Which makes it partially permeable
