Morphological changes are indicative of deficiencies of certain elements are called deficiency symptoms.
For actively mobilised elements within plant exported to young tissues and deficiency symptoms  tend to appear first in older tissues.
Deficiency symptoms tend to appear in the young tissues whenever the elements are relatively immobile and are not transported out of mature organs.
This aspect of mineral nutrition is of great significance and importance in agriculture and horticulture.
