Q. No.The deficiency symptoms of mobilizable substances appear first in Older parts because
(1) In order to mobilize the elements to young part, the biomolecules of older parts are broken down
(2) In order to mobilize the elements the older part becomes weaker
(3) The work of mobilization is random and takes a lot of energy to cause it
(4) All of these
(1) In order to mobilize the elements to young part, the biomolecules of older parts are broken down
(2) In order to mobilize the elements the older part becomes weaker
(3) The work of mobilization is random and takes a lot of energy to cause it
(4) All of these
The elements which are not actively mobilizable or immobilized within the plants. The deficiency symptom is observed in
(1) Both in young and old parts
(2) Only in young parts
(3) First in old parts
(4) First in young parts
The deficiency symptoms of how many elements will be appearing in older tissue first?
N,K,Mg,S,Ca
(1) Zero
(2) Three
(3) Two
(4) Four
The deficiency symptoms of S and Ca will appear first in
(1) Both in young and old parts
(2) Only in young parts
(3) First in old parts
(4) First in young parts
Why does S and Ca deficiency not found in older parts first?
(1) As they are immobilizable
(2) As they are very abundant in older parts
(3) As newer parts are already deficient
(4) Both A and B
The knowledge of deficiency symptoms of mobilizable and immobilizable substances actually helps in
(1) Horticulture
(2) Agriculture
(3) Both A and B
(4) Pisciculture
Chlorosis is not
(1) Loss of chlorophyll
(2) Leading to yellowing of leaves
(3) Deficiency of elements N, K, Mg, S, Fe, Mn, Zn and Mo
(4) Accumulation of mutated chlorophyll
Which of the following elements does not cause both an inhibition of cell division and delay in flowering if their concentration in plants is low?
(1) N
(2) K
(3) S
(4) Mo
The following statements are correct except
(1) Different plants respond differently to the deficiency of the same element
(2) The deficiency of any element can cause multiple symptoms and that the same symptoms can be caused by the deficiency of other elements as well
(3) Lack of N, K, S, Mo is responsible for cell division
(4) There is a narrow range of concentration at which elements are optimum
