With respect to trap leaves of Nepenthes. The incorrect match is

Options

A. Upper petiole - Tendril
B. Lower petiole-Phyllode
C. Leaf apex - Lid
D. Leaf apex - Pitcher

Answer

To determine the incorrect match with respect to the trap leaves of Nepenthes, we need to analyze the structure and function of different parts of the plant. Here’s a step-by-step breakdown:

### Step 1: Identify the Structure of Nepenthes
Nepenthes, commonly known as the pitcher plant, has specialized leaves that form a pitcher-like structure. This structure is designed to trap insects for nutrient absorption.

### Step 2: Analyze the Upper Pitiole
The upper pitiole, or the upper part of the leaf stalk, is known to form tendrils. These tendrils help the plant climb and support itself. This match is correct.

### Step 3: Analyze the Lower Pitiole
The lower pitiole is involved in forming phyllodes, which are leaf-like structures that can assist in photosynthesis and provide support. This match is also correct.

### Step 4: Analyze the Leaf Apex
The leaf apex is the tip of the leaf. In the case of Nepenthes, it is important to note that the pitcher structure is not formed by the leaf apex but rather by the leaf lamina (the broader part of the leaf). Therefore, this match is incorrect.

### Step 5: Identify the Mismatch
The mismatch is found in the association of the leaf apex with the formation of the pitcher. The pitcher is actually formed from the leaf lamina, not the leaf apex. Thus, the incorrect match is the one that links the leaf apex with the pitcher formation.

### Conclusion
The incorrect match regarding the trap leaves of Nepenthes is the association of the leaf apex with the formation of the pitcher. The correct structure responsible for the pitcher formation is the leaf lamina.
