:: Wnt, Thank you for this detailed, and generous answer, You helped me very much !, I just have one little question to see I understand you properly : Is Molecular Apolarity differs from Covalent Apolarity ? ( The Covalent bonds at the formula above seems Polar to me, i . e from different elements, and yet you titled the molecule itself as Apolar ) . talk ) 23 : 17, 19 October 2014 ( UTC)

According to the chemioosmotic model, PAT results from the combination of three processes 1 ) The " apolar influx " of auxin into the cells by passive diffusion of the acidic form of auxin across the membrane; 2 ) The dissociation and subsequent " trapping " of auxin under its anionic form in the cell; and 3 ) the " polar efflux " of the anionic form of auxin through the activity of polarised auxin efflux carriers.
