Question

Assertion (A): In Nepenthes, the upper petiole is modified as tendril and lower petiole as phyllode and middle lamina as pitcher.
Reason (R): This is to trap insects for their nitrogen requirement.
Identify the correct option from the following

• (A) and (R) are true. (R) is correct explanation for (A)
• (A) and (R) are true. (R) is not correct explanation for (A)
• (A) is true, but (R) is false
• (A) is false, but (R) is true

Hint:

Insectivorous plants modify leaf parts to meet nutritional deficiencies — especially nitrogen.

Answer 1

The Correct Option is A

Nepenthes (pitcher plant) shows modification of leaves to trap insects.
The upper petiole becomes a tendril for climbing, the lower becomes a phyllode, and the middle lamina turns into a pitcher.
This adaptation helps them obtain nitrogen in nutrient-poor soils. Hence, both assertion and reason are correct, and (R) explains (A).
