Totipotency is the ability of a cell to differentiate and give rise to a whole new organism. Totipotency is exhibited by the cells such as embryonic stem cells that can differentiate into any type of body cell.

Identify ‘A’ in the chart given below: Product Plant (1) Nicotine Nicotiana tabacum (2) Vincristin, Vinblastin 'A'

In the given chart, 'A' represents Catharanthus roseus from which Vincristin and Vinblastin alkaloids are obtained . Many useful secondary metabolites can be produced by a cell or suspension culture. These may be alkaloids, allergens, antitumor agents, enzymes, hormones, etc. Nicotine is a secondary metabolite obtained from the Nicotiana tabacum plant.
