Answer» Correct Answer - C There are two phases during process of mineral ion absorption---initial phase and metabolic phase. In the initial phase, there is a rapid uptake of ions into outer or free space (intercellular spaces and cell walls) of cells. Ions absorbed in free space are freely exchangeable. Entry of ions into outer space is passive absorption as no energy is required for it. |
