Question

Match the LIST-I with LIST-II

• A. A-IV, B-III, C-I, D-II
• B. A-IV, B-II, C-I, D-III
• C. A-IV, B-I, C-II, D-III
• D. A-IV, B-I, C-III, D-II

Hint:

Morphological Modifications:
Nepenthes = Pitcher leaf.
Lathyrus = Leaf tendril.
Asparagus = Cladode (modified stem).
Utricularia = Bladder leaf.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
The question asks to match plant genera in LIST-I with their corresponding specialized morphological leaf or stem modifications in LIST-II.

Step 2: Key Formula or Approach:
Identify plant organ adaptations:
• Nepenthes: Insectivorous pitcher plant (leaf lami modified into pitcher).

• Lathyrus: Sweet pea (leaflets modified into climbing tendrils).

• Asparagus: Modified photosynthetic green stem of limited growth (cladode).

• Utricularia: Aquatic insectivorous bladderwort (leaf segments modified into trap bladders).

Step 3: Detailed Explation:

• A. Nepenthes $\to$ IV. Pitcher: In Nepenthes, the leaf lami is modified into a pitcher-shaped trap equipped with digestive enzymes to capture insects.

• B. Lathyrus $\to$ III. Tendril: In Lathyrus odoratus (sweet pea), the upper leaflets are modified into sensitive coiled tendrils for climbing support.

• C. Asparagus $\to$ I. Cladode: Asparagus develops flattened, green photosynthetic branch stems of limited growth called cladodes while leaves are reduced to scales.

• D. Utricularia $\to$ II. Bladder: In Utricularia (bladderwort), aquatic leaf segments form tiny suction bladders to trap small aquatic invertebrates.

Step 4: Fil Answer:
The correct matching sequence is A-IV, B-III, C-I, D-II.
