Secondary Metabolites Plant Species Matching Solution
This question requires matching secondary metabolites listed in Column-I with their respective plant species in Column-II.
Step 1: Match Morphine
Morphine is a well-known alkaloid primarily extracted from the opium poppy.
- Morphine (P) corresponds to Papaver somniferum (3).
Step 2: Match Vincristine
Vincristine is a crucial chemotherapy agent derived from the Madagascar periwinkle.
- Vincristine (S) corresponds to Catharanthus roseus (2).
Step 3: Match Scopolamine
Scopolamine (also known as Hyoscine) is found in several Solanaceae family plants, including Jimsonweed.
- Scopolamine (R) corresponds to Datura stramonium (1).
Step 4: Match Pyrethrins
Pyrethrins are natural insecticides. Based on the provided options, this metabolite is linked to *Tagetes erecta*.
- Pyrethrins (Q) corresponds to Tagetes erecta (4).
Step 5: Final Combination
Combining the matches from the previous steps gives the correct pairing:
- P-3
- Q-4
- R-1
- S-2
This corresponds to Option 2 (P-3, Q-4, R-1, S-2).
Important Questions from Production of Secondary Metabolites
- Which of the following plant-based secondary metabolites belong(s) to the class of alkaloids?
- 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
Vincristine and vinblastine, two commercially important secondary metabolites from Catharanthus roseus, are examples of ______
