Question

Upper part of petiole is modified into tendril in?

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [B]
## CONCEPT FRAMEWORK
	**Primary Concept**: Plant morphology and modifications
	**Related Topics**: Tendrils, petioles, plant adaptations
	**Prerequisites**: Basic knowledge of plant parts and their functions
## SOLUTION PATHWAY
**Given Information**:
	The question asks about which plant has a petiole modified into a tendril.
**Method & Steps**:
	1. Recall the definition of a petiole: The stalk that attaches the leaf blade to the stem.
	2. Recall the definition of a tendril: A threadlike, leafless organ that twines around support structures, aiding in climbing.
	3. Consider each option:
		- A. Pisum (Pea): Tendrils are modified leaflets, not petioles.
		- B. Nepenthes (Pitcher Plant): The upper part of the petiole is modified into a tendril in some species.
		- C. Bean: Tendrils are not present in common bean plants.
		- D. Cuscuta (Dodder): This is a parasitic plant; it lacks petioles and has twining stems, not tendrils from petioles.
	4. Identify the correct option based on recall of plant modifications
## OPTION ANALYSIS
[A] :x: Pisum uses modified leaflets as tendrils.
[B] ✓: In some species of Nepenthes, the upper part of the petiole is modified into a tendril.
[C] :x: Bean plants do not have tendrils from petioles.
[D] :x: Cuscuta is a parasitic plant with twining stems, not petiole tendrils.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing tendrils derived from different plant parts (e.g., leaflet vs. petiole):
			- How to avoid: Carefully study diagrams and examples of tendril modifications in different plant species.
	**Quick Tips**:
		1. Visualizing plant structures and their modifications can help in recalling information.
		2. Remember specific examples of plants with unique adaptations.
