Question

Identify the correct matching: \renewcommand{\arraystretch}{1.3} \begin{table}[h!] \centering \setlength{\tabcolsep}{15pt} \begin{tabular}{|c|l|c|l|} \hline Column I & Plant Name & Column II & Feature
\hline I & Nerium & = Verticillaster & = Sunken stomata
II & Vallisnaria & = Free floating hydrophyte & = Epihydrophily
III & Tribulus & = Emphemeral & = Xerophyte
IV & Rhizophora & = Halophyte& = Vivipary
\hline \end{tabular} \end{table}

• A. I and III
• B. II and IV
• C. I and II
• D. \textbf{III and IV} \

Hint:

Different plants exhibit specialized adaptations for survival in their environments. Xerophytes (e.g., Tribulus) have adaptations to survive in dry conditions, while mangroves (e.g., Rhizophora) exhibit vivipary, where seeds germinate before dispersal.

Answer 1

The Correct Option is D

Step 1: Understanding the correct matching - I - Nerium = Sunken Stomata (Correct)
- Nerium is a xerophytic plant that has sunken stomata to reduce transpiration.
- II - Vallisnaria = Epihydrophily (Correct)
- Vallisneria undergoes epihydrophily, meaning pollination occurs on the water surface.
- III - Tribulus = Xerophyte (Correct)
- Tribulus is a xerophyte, meaning it is adapted to dry environments.
- IV - Rhizophora = Vivipary (Correct)
- Rhizophora (mangrove) exhibits vivipary, where seeds germinate while still attached to the parent plant.
Step 2: Examining the given options
- Option 1 (I and III) → Incorrect (Only III is correct).
- Option 2 (II and IV) → Incorrect (Both II and IV are correct, but III is missing).
- Option 3 (I and II) → Incorrect (Both are correct but not the best match).
- Option 4 (III and IV) → Correct, as both matches are accurate.
Step 3: Conclusion Since the correct matching includes Tribulus = Xerophyte and Rhizophora = Vivipary, the correct answer is Option (4).
