In virus-infected plants the meristematic tissues in both apical and axillary buds are free of virus because
The meristematic tissues are free from virus because the spread of virus in the plant tissue does not keep up that means the growth of meristems are faster than the viral multiplication. Generally shoot apical meristems are virus free mostly as they actively producing new leaves and flowers.
So, the correct option is 'Option C, The cell division of meristems are faster than the rate of viral multiplication'.
Mention the ploidy of the following: 1. Protonemal cell of a moss, 2. Primary endosperm nucleus in dicot, 3. Leaf cell of a moss, 4. Prothallus cell of a fern, 5. Gemma cell in Marchantia, 6. Meristem cell of a monocot, 7. Ovum of a liverwort, 8. Zygote of a fern.
