Question

Common symptoms due to viral infection includeA. necrosisB. mosaic formationC. chlorosisD. all of these

Answer 1

All of the above are symptoms of viral infection. Necrosis is a form of cell injury resulting in the premature death of cells in the living tissue.

Mosaic formation involves the presence of two or more population of cells in one individual developing from a single fertilized egg.

Chlorosis is a very common symptom of viral infection in plants where the leaves don’t have enough nutrient for the synthesis of chlorophyll, hence get discoloured.
