Q. To obtain virus- free healthy plants from a diseased one by tissue culture technique, which part/parts of the diseased plant will be taken?

(a) Epidermis only

(b) Apical meristem only

(c) Palisade parenchyma

(d) Both apical and axillary meristems

Solution :

Correct Option : D The meristem is the tissue in plants that contain undifferentiated cells or meristematic cells which are rapidly dividing cells and thus are the virus-free part of the diseased plant. The culture with meristem has enabled the production of disease-free varieties including virus-free healthy plants.
Thus, the correct answer is option D.
