Solution
The correct option is C Apical meristem cells
When the apex of a shoot is used for multiplication by tissue culture, we get disease-free plants because the shoot apical meristem, a group of dividing cells at the tip of a stem or root, is free from pathogens. Genetically identical plants derived from an individual are called clones. Micropropagation by tissue culture helps in producing clones. Using the shoot tip, it is possible to obtain a large number of plantlets. This technique is used extensively in the commercial field for micropropagation of ornamental plants like chrysanthemum, gladiolus, etc., and also crops such as sugar cane, tapioca, and potato. Plants are grown from tissue culture usually pass trough callus phase and show many variations. These show some agronomic characteristics like tolerance to pests, diseases, etc.
