Question:
Which of the following climber possesses special structure- tendrils to climb over a support?
Which of the following climber possesses special structure- tendrils to climb over a support?
Show Hint
Tendrils can be modified stems (e.g., Grapes), modified leaves (e.g., Sweet Pea), or modified inflorescences (e.g., Antigonon).

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Climbers have evolved various morphological adaptations to grow vertically. These include twiners, root climbers, hook climbers, and tendril climbers.
Step 2: Detailed Explanation:
Bougainvillea peruviana: This is a "hook climber" or "scrambler." It uses sharp, woody thorns (modified stems) to hook onto nearby vegetation or structures. It does not produce tendrils.
Ficus repens (Creeping Fig): This is a "root climber." It produces small adventitious "adhesive" roots along its stem that cling directly to surfaces like walls or tree trunks.
Quisqualis indica (Rangoon Creeper): This is a "woody twiner" or "straggler." The entire stem twists around a support to climb. While it may occasionally use persistent leaf stalks as hooks, it is not a tendril climber.
Antigonon leptopus (Coral Vine): This plant is a quintessential "tendril climber." It produces specialized, sensitive, thread-like structures called tendrils at the ends of its flower clusters (inflorescences). These tendrils coil around any support they touch, providing the necessary mechanical leverage for the vine to climb.
Step 3: Final Answer:
Antigonon leptopus is the climber that uses tendrils to climb.
