A is a plant in which the petiole is modified into leaf like structure B is a plant in which upper part of the petiole is modified into tendril. Identify A & B

Options

A. Australian Acacia, Nepenthes
B. Zizyphus and Acacia
C. Nepenthes and Drosera
D. Drosera and Dionaea

Answer

To solve the question, we need to identify two plants based on the modifications of their petioles. Let's break down the solution step by step:

### Step 1: Understand the Modifications
- **Plant A**: The petiole is modified into a leaf-like structure.
- **Plant B**: The upper part of the petiole is modified into a tendril.

### Step 2: Identify Plant A
- We need to find a plant where the petiole is modified into a leaf-like structure.
- One such plant is **Australian Acacia**, where the petiole takes on the role of a leaf, often referred to as a phyllode.

### Step 3: Identify Plant B
- Now, we need to find a plant where the petiole is modified into a tendril.
- A well-known example of this is **Nepenthes**, which is a genus of carnivorous plants that have tendrils formed from the petiole.

### Step 4: Match with Options
- Now we can match our findings with the given options:
1. Australian Acacia and Nepenthes
2. Zygophyllum and Acacia
3. Nepenthes and Rosera
4. Rosera and Duneilac

- The correct option is **1: Australian Acacia and Nepenthes**.

### Final Answer
- **Plant A**: Australian Acacia (petiole modified into leaf-like structure)
- **Plant B**: Nepenthes (upper part of the petiole modified into tendril)
