Question

Choose the correct answer from the alternatives given.
Absence of $M{g}^{++}$ ions from plant tissues results in:

• A. Plasmolysis
• B. Hydrolysis
• C. Chlorosis
• D. Necrosis

Answer 1

The correct option is C Chlorosis

Excess potassium, generally due to fertilizers, further aggravates the stress from magnesium deficiency, as does aluminium toxicity. This causes the main symptom of magnesium deficiency, interveinal chlorosis, or yellowing between leaf veins, which stay green, giving the leaves a marbled appearance. So, the correct answer is "Chlorosis".
