Step-by-step solution
Even if the plant is infected with a virus, the meristem is free of virus. One can remove the meristem and grow it in vitro to obtain virus-free plants. Scientists have succeeded in culturing meristems of banana, sugarcane, potato, etc. Scientists have isolated single cells from plants and after digesting their cell walls have been able to isolate naked protoplasts.
