Question

Explain Chlorosis and Necrosis?

Answer 1

Chlorosis: 

• Due to the degradation of chlorophyll, the leaves become decolourized and become pale yellow coloured. 
• This effect is called chlorosis. 
• Deficiency of Mg, N, Fe, and Mn etc. result in chlorosis. 

Necrosis: 

• Death or degradation of cells of plant tissue is called necrosis. 
• Due to this effect, the leaves show spots, rotting, or blight symptoms.
• Deficiency of Ca, Mg, Cu, and K etc. causes necrosis of cells.
