SSC MTS EXAM

Detailed explanation-1: -Chlorosis: Chlorosis or loss of chlorophyll leads to the yellowing of leaves. It is caused by the deficiencies of nitrogen, potassium, magnesium, sulphur, iron, manganese, zinc, and molybdenum. Necrosis: Necrosis is the death of plant tissues as a result of the deficiencies of calcium, magnesium, copper, and potassium.

Detailed explanation-2: -In most plants, young foliage is severely stunted as well as chlorotic. Deficient foliage can be cupped and deformed (tung), bleached (lettuce), flaccid and blue green with chlorotic margins (tomato), abscise early (walnut), and eventually become necrotic in the interveinal areas (tung).

Detailed explanation-3: -As magnesium is the important element in chlorophyll, deficiency of magnesium causes chlorosis.

Detailed explanation-4: -Manganese or zinc or magnesium deficiencies within the plant also will cause chlorosis. Deficient nitrogen or proteins can also cause chlorosis. Hence in plants, chlorosis is caused by the deficiency of nitrogen, manganese, magnesium.
