Solution
The correct options are A active D passive The mechanism of mineral absorption can happen in two ways:
Apoplastic pathway where ions are taken up into the free space or outer space of the cell passively along the concentration gradient.
Symplastic pathway: This is the second phase where the ions move into the cell through ion-channels powered by the energy generated by breaking up of ATP.
