Question

In tissue culture experiments of tobacco callus, it was seen that when the culture medium contains 2 ppm of IAA and 2 ppm of kinetin, an undifferentiated mass of callus is produced. If the ratio of kinetin to IAA is increased, then (A) The callus size would increase by repeated cell divisions (B) Root initiation would take place (C) Shoot initiation would occur (D) The callus would die

Tardigrade Admin · Accepted Answer

Kinetin causes organogenesis in tissue culture.
Kinetin is a type of cytokinin, a class of plant hormone that promotes cell division. Kinetin was originally isolated by Miller and Skoog et al. as a compound from autoclaved herring sperm DNA that had cell division-promoting activity.
