Chlorosis is the yellowing and paling of leaves which might
be due to deficiency of Mg, Fe, Zn or Nitrogen or excess of
Cl while necrosis is browning or burning of the plant
tissues due to deficiency of K or/and Ca, or excess of Na.
It can also be observed in form of black or brown spots on
leaves.

Answer / dipul kumar biswas
Chlorosis is a yellowing of leaf tissue due to a lack of
chlorophyll. Possible causes of chlorosis include poor
drainage, damaged roots, compacted roots, high alkalinity,
and nutrient deficiencies in the plant
Necrosis is death of body tissue. It occurs when there is
not enough blood to the tissue, whether from injury,
radiation, or chemicals. Necrosis is not reversible.
When substantial areas of tissue die due to a lack of blood
supply, the condition is called gangrene.
