I) Mention the property that enables the explants to regenerate into a new plant. II) a banana - herb is virus infected. Describe the method that will help in obtaining healthy banana plants from this diseased plant.

Dear student

Please refer the solution below for the said query


(I). Totipotency is the property that enables the explants to regenerate into a new plant.

(II). Meristem tissue culture is the method that will help in obtaining healthy banana plants from this diseased plant. 
Apical and axillary meristems of plants are mainly used for making virus-free plants. Apical or axillary meristem tissue called explants are grown in sterile conditions in special nutrient media to regenerate complete plants. Nutrient media contain a carbon source (such as sucrose), inorganic salts, vitamins, amino acids and phytohormones. The cells of explant divide inside the nutrient medium to produce a mass of undifferentiated cells called callus. The callus then differentiates to produce roots and shoots by regulating concentration of phytohormones like auxins and cytokinins in medium. Hence, propagation is achieved for a large number of plants in a short duration. This process is also called micropropagation.


Hope this information clears your doubt about the topic.
