Answer

To solve the question of selecting an incorrect statement, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Analyze the first statement:**
- **Statement:** "Leaves are often converted into tendrils for climbing as in peas."
- **Analysis:** This statement is correct. In plants like peas, leaves can indeed transform into tendrils that help the plant climb.

2. **Analyze the second statement:**
- **Statement:** "Leaves are often converted into spines in cacti."
- **Analysis:** This statement is also correct. In cacti, leaves are modified into spines to reduce water loss and protect against herbivores.

3. **Analyze the third statement:**
- **Statement:** "In Australian Acacia, the leaves are large but short-lived."
- **Analysis:** This statement is incorrect. In Australian Acacia, the leaves are typically small and short-lived. The petiole (the stalk that attaches the leaf blade to the stem) can expand and become green, functioning similarly to a leaf for photosynthesis.

4. **Analyze the fourth statement:**
- **Statement:** "The fleshy leaves of onion and garlic store foods."
- **Analysis:** This statement is correct. The fleshy leaves of onion and garlic are indeed modified for storage of food.

### Conclusion:
The incorrect statement among the options is the third one: "In Australian Acacia, the leaves are large but short-lived."
