Solution: The meristematic tissues are virus-free because virus spread in plant tissue does not keep up with meristem growth, which means meristem growth outpaces viral multiplication. Since they are actively developing new leaves and flowers, shoot apical meristems are often virus-free. Meristem cell division is faster than viral multiplication. So, the correct option is (c).
In virus-infected plants, the meristematic tissues in both apical and axillary buds are free of the virus because:
a. the dividing cells are virus-resistant
b. meristems have anti-viral compounds
c. the cell division of meristems is faster than the rate of viral multiplication
d. Viruses cannot multiply within the meristem cell (s).
a. the dividing cells are virus-resistant
b. meristems have anti-viral compounds
c. the cell division of meristems is faster than the rate of viral multiplication
d. Viruses cannot multiply within the meristem cell (s).
