The following statements are associated with translocation
of mineral ions.
(i) Mineral ions are slowly remobilised.
(ii) Younger leaves export most of their minerals content
to older leaves.
(iii) Elements most readily mobilised are P, S, N and K.
(iv) Some elements that are structural components like
calcium are not remobilised.
Which of the above statements are correct?
(a) (i) and (iii) (b) (i) and (ii)
(c) (iii) and (iv) (d) (ii) and (iii)
Answer: (c) Statements (iii) and (iv) regarding translocation of mineral ions are correct. (i) Mineral ions are frequently remobilised, particularly from older senescing parts. (ii) Older drying leaves export much of their mineral contents to younger leaves
