Q.47 Match List I with List II
| List I (Plants source) | List II (Uses) |
|---|---|
| A. Allium sativa B. Coptis japonica C. Taxus baccata D. Digitalis lanata |
I. Anticarcinogenic II. Cardiac medicine III. Insecticidal IV. Antibacterial |
Choose the correct answer from the options given below:
Allium sativa, Coptis japonica, Taxus baccata, and Digitalis lanata are key medicinal plants tested in exams like NEET. This matching question links their sources to specific uses: anticarcinogenic, cardiac medicine, insecticidal, and antibacterial. The correct option reveals their pharmacological roles in biology.
Correct Answer
The right match is (C) (A) – (III), (B) – (IV), (C) – (I), (D) – (II).
-
A. Allium sativa (Garlic) → III. Insecticidal: Garlic’s allicin compound repels insects and has pesticidal effects alongside antibacterial properties.
-
B. Coptis japonica → IV. Antibacterial: Its berberine alkaloid fights bacterial infections, dysentery, and gastrointestinal issues effectively.
-
C. Taxus baccata (Yew) → I. Anticarcinogenic: Produces taxol (paclitaxel), a chemotherapy drug targeting cancer cells.
-
D. Digitalis lanata → II. Cardiac medicine: Yields digoxin, used for heart conditions like atrial fibrillation and heart failure.
Option Analysis
Each option tests precise plant-use links, common in molecular biology and pharmacology exams.
| Option | A (Allium sativa) | B (Coptis japonica) | C (Taxus baccata) | D (Digitalis lanata) | Status |
|---|---|---|---|---|---|
| (A) | I. Anticarcinogenic | II. Cardiac | III. Insecticidal | IV. Antibacterial | Incorrect |
| (B) | I. Anticarcinogenic | III. Insecticidal | II. Cardiac | IV. Antibacterial | Incorrect |
| (C) | III. Insecticidal | IV. Antibacterial | I. Anticarcinogenic | II. Cardiac | Correct |
| (D) | I. Anticarcinogenic | IV. Antibacterial | III. Insecticidal | II. Cardiac | Incorrect |
Option (C) aligns with established uses: garlic for pest control, Coptis for infections, yew for cancer therapy, and foxglove for heart drugs.
Plant Uses Breakdown
These plants highlight natural products in medicine, relevant for biochemistry and exam prep.
Allium sativa (Garlic)
Contains sulfur compounds like allicin with insecticidal action against pests; also antibacterial but matched here to insects.
Coptis japonica (Goldthread)
Berberine provides strong antibacterial effects against dysentery and infections; traditional East Asian remedy.
Taxus baccata (English Yew)
Taxanes like paclitaxel inhibit cancer cell division, making it anticarcinogenic; key in oncology.
Digitalis lanata (Woolly Foxglove)
Cardiac glycosides (digoxin, digitoxin) strengthen heart contractions for congestive heart failure.
This matching reinforces pharmacognosy knowledge for biology students focusing on plant-derived drugs.
