Plant Sources, Metabolites, and Medical Uses
This question requires matching specific plant sources with their corresponding secondary metabolites and documented medical uses.
Matching Plant Sources, Metabolites, and Uses
- P. Belladonna: This plant is a natural source of the alkaloid Atropine (metabolite 2). Atropine is medically used primarily for Eye examination (use c) to dilate pupils. Thus, the match is P-2-c.
- Q. Foxglove: The Foxglove plant yields cardiac glycosides, notably Digitalis (metabolite 3). Digitalis is crucial in treating various Heart disease conditions (use b). Thus, the match is Q-3-b.
- R. Pacific yew: The bark of the Pacific yew tree contains Taxol (metabolite 4), a potent chemotherapy drug used in Cancer treatment (use a). Thus, the match is R-4-a.
- S. Eucalyptus: Eucalyptus leaves and oil contain compounds like Menthol (metabolite 1). Menthol is commonly used for its decongestant properties, providing relief for Cough and respiratory issues (use d). Thus, the match is S-1-d.
Final Matching Summary
Combining these individual matches results in the complete set:
- P - 2 - c (Belladonna - Atropine - Eye examination)
- Q - 3 - b (Foxglove - Digitalis - Heart disease)
- R - 4 - a (Pacific yew - Taxol - Cancer treatment)
- S - 1 - d (Eucalyptus - Menthol - Cough)
This corresponds to the combination P-2-c, Q-3-b, R-4-a, S-1-d.

- Which one of the following plant secondary metabolites is a natural insecticide?
Determine the correctness or otherwise of the following Assertion and Reason (r).
Assertion: The production of secondary metabolites in plant cell cultures is enhanced by the addition of elicitors.
Reason: Elicitors induce the expression of enzymes responsible for the biosynthesis of secondary metabolites.
- The pungency of mustard seeds is primarily due to secondary metabolites such as isothiocyanate and nitrile. The pungency is usually felt only when the seeds are crushed. This is because of
