Match List I with List II
Show Hint
- Direct penetration: Magnaporthe (appressorium).
- Stomata: Puccinia (rusts).
- Hydathodes: Xanthomonas (bacterial leaf spots).
- Wounds: Agrobacterium (requires wound for entry).
- A (IV), B (I), C (II), D (III)
- A (I), B (II), C (III), D (IV)
- A (IV), B (III), C (II), D (I)
- A (I), B (IV), C (II), D (III)
The Correct Option is A
Solution and Explanation
This question tests knowledge of how plant pathogens enter host tissues.
Step 2: Detailed Explanation:
Magnaporthe oryzae (A): Enters by direct penetration (IV) (appressorium formation).
Puccinia tritici (B): Enters through stomata (I) (germ tube enters via stomata).
Xanthomonas axonopodis (C): Enters through hydathodes (II) (natural openings).
Agrobacterium tumefaciens (D): Enters through wounds (III) (requires wound site).
Thus, the correct matching is A (IV), B (I), C (II), D (III).
Step 3: Final Answer:
Thus, the correct answer is A (IV), B (I), C (II), D (III), which corresponds to option (A).
