BIOXII09: STRATEGIES FOR ENHANCEMENT IN FOOD PRODUCTION

343711 In virus-infected plants the meristematic tissues in both apical and axillary buds are free of virus because:

1 The dividing cells are virus resistant
2 Meristems have antiviral compounds
3 The cell division of meristems is faster than the rate of viral multiplication
4 Viruses cannot multiply within meristem cell (s).

343712 The phenomenon of the reversal of mature cells to the dividing state leading to the formation of callus is known as

1 Redifferentiation
2 Dedifferentiation
3 Either \(a\) or b
4 None of these
