The elements which are actively mobilizable within the plant body and are exported to young developing plant parts, their deficiency symptom will be first 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 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
