Vedclass · Answer

(B) The absorption of minerals occurs in two phases. In the first phase,an initial rapid uptake of ions into the free space or outer space of cells occurs,which is a passive process. In the second phase,ions are taken into the inner space (the cytoplasm or vacuole) of the cells. This movement of ions into the inner space is against the concentration gradient and requires metabolic energy,therefore it is called active uptake.

For the uptake of ions in the second phase of absorption of minerals,the pathway followed is called
