The mechanism of absorption of minerals can occur in two main phases.
i. In the first phase, the apoplast is passive and uptake of ions into the ‘free space’ or ‘outer space’ of cells occurs.
ii. The ions are taken in slowly into the ‘inner space’ the symplast of the cells in the second phase.
The ion channels, the transmembrane proteins that function as selective pores help in the passive movement. The expenditure of metabolic energy is required for the entry or exit of ions to and from the symplast. The inward movement of molecules into the cells is influx and the outward movement is efflux.Answered by Pragya Singh | 1 year ago
Which of the following statements are true? If false, correct them.
i. Boron deficiency leads to stout axis.
ii. Cell needs every mineral element that is present in it.
