Vedclass · Answer

(D) Mineral absorption in plants occurs in two distinct phases:$(i)$ Initial phase: Ions are rapidly taken up into the 'outer free space' or the $apoplast$ of the cells. This is a passive process that does not require metabolic energy.$(ii)$ Final phase: Ions are slowly transported into the 'inner space' or the $symplast$ of the cells. This is an active process that requires metabolic energy in the form of $ATP$.$(iii)$ The passive movement of ions into the $apoplast$ is facilitated by ion channels,which are transmembrane proteins acting as selective pores for specific ions.Therefore,all the given statements are correct.
