Question

Which of the following correctly matches the organism with its classification group?

Choose the correct match:

1. A. Only II (Correct answer)
2. B. Only I and II
3. C. Only II and IV
4. D. All of the above

Correct Answer

Option A — Only II

Detailed Solution & Explanation

The correct answer is Only II.

Key Points

• Examining each pair:
  • I. Rose — Monocotyledon: INCORRECT. The rose (*Rosa*) is a dicotyledon. Its seeds have two cotyledons, its leaves show reticulate (net-like) venation, and its floral parts occur in fours or fives.
  • II. Frog — Amphibian: CORRECT. The frog belongs to Class Amphibia, living both in water and on land, with moist permeable skin, external fertilisation and an aquatic larval (tadpole) stage.
  • III. Mango — Gymnosperm: INCORRECT. The mango (*Mangifera indica*) is an angiosperm — its seeds are enclosed within a fruit. Gymnosperms bear naked seeds and produce no true fruit.
  • IV. Shark — Reptile: INCORRECT. The shark is a fish, belonging to Class Chondrichthyes, the cartilaginous fishes. It breathes through gills and has a skeleton of cartilage rather than bone.
• Only pair II is correctly matched.

Additional Information

• Monocots versus dicots:

• Angiosperms versus gymnosperms: angiosperms bear enclosed seeds within fruits and have flowers; gymnosperms bear naked seeds on cones — pine, deodar, cycas, *Ginkgo*. Deodar (*Cedrus deodara*) is the well-known gymnosperm of Jammu & Kashmir's forests.
• Chondrichthyes versus Osteichthyes: sharks, rays and skates have cartilaginous skeletons, no operculum and no swim bladder; bony fishes such as rohu and tuna have bony skeletons, an operculum covering the gills, and a swim bladder.
