Detailed explanation-1: -Chlorosis is a condition in plants due to a lack of chlorophyll. It results in the yellowing of leaves of plants. It mainly happens due to a lack of nutrients to synthesize sufficient chlorophyll. It can be cured by providing nutrients such as magnesium, zinc, sufficient sunlight, etc.

Detailed explanation-2: -Yellowing of the areas between the veins (interveinal chlorosis) is usually indicative of manganese, iron or magnesium deficiency. Iron deficiency affects the youngest leaves first, whereas the symptoms of manganese and magnesium deficiency tend to start in the older leaves.

Detailed explanation-3: -Chlorosis refers to the yellowing of plant parts, mainly leaves and veins. Yellow spots appear on the leaves, giving a mosaic pattern. Yellowing occurs due to insufficient amounts of chlorophylls. Chlorophyll production can be decreased due to many reasons.
