Options:
Answer:
Solution:
Copper deficiency usually results in shriveling or malformation of the leaves along with tip burn. The most easily recognized symptoms of copper deficiency are those in a disease of fruit trees called "exanthema".
Magnesium plays two very essential roles in the processes of photosynthesis and carbohydrate metabolism. Magnesium deficiencies show up as extensive chlorosis between the veins of the leaves. Chlorosis is followed by the appearance of anthocyanin pigments in the leaves such as the oranges, reds, and purples.
Iron functions in the synthesis of chloroplastic protein and thus may interfere with chlorophyll synthesis. Iron deficiencies of plant leaves appear as extensive chlorosis in the foliage.
