In which of the following plants, the leaves are small and short-lived, the petioles expand and become photosynthetic to form phyllode ?

Options

A. Pitcher Plant
B. Bombar
C. Australian acacia
D. Centella

Answer

To determine which plant has small and short-lived leaves, where the petioles expand and become photosynthetic to form phyllodes, follow these steps:

### Step 1: Understand the Key Terms
- **Leaves**: Typically, the primary function of leaves is to perform photosynthesis.
- **Petioles**: The stalk that attaches the leaf blade to the stem.
- **Phyllodes**: Modified petioles that take on the function of leaves, often becoming flattened and green to perform photosynthesis.

### Step 2: Analyze the Options
- **A. Pitcher plant**: Known for its modified leaves that form a pitcher shape to trap insects, not relevant to the question.
- **B. Bomber**: Not a commonly known plant in this context, and does not typically have phyllodes.
- **C. Australian Acacia**: Known for having small, short-lived leaves, where the petioles expand and become photosynthetic, forming phyllodes.
- **D. Candela**: Not known for having phyllodes; typically does not fit the description.

### Step 3: Identify the Correct Answer
Based on the analysis, the plant that fits the description of having small and short-lived leaves, with petioles that expand and become photosynthetic to form phyllodes, is **C. Australian Acacia**.

### Conclusion
The correct answer to the question is **C. Australian Acacia**.
