Not in NEET syllabus

Which of the following statements are correct about mineral absorption in plants?

(A)In the initial phase, ions are taken up into the outer space of cells, the apoplast; it is a passive process
(B)In the final phase, ions are taken up slowly into the inner space, the symplast of cells, and this is an active process
(C)Passive movement of ions into the apoplast occurs through ion channels, transmembrane proteins that act as selective pores
(D)All of the aboveCorrect

Answer: (D)

Solution

Mineral ion uptake occurs in two steps: a rapid, passive initial phase moving ions into the outer free space (apoplast, via ion channels acting as selective pores), followed by
