Vedclass · Answer

(C) : Meristem is a localized group of cells,which are actively dividing and undifferentiated but ultimately give rise to permanent tissue.Even if the plant is infected with a virus,the meristematic tissue remains free of the virus.Therefore,the meristem can be removed and grown in vitro to obtain virus-free plants.Cultivation of axillary or apical shoot meristems is called meristem culture.Both apical and axillary meristems are generally free from viruses.
