Options

A. Phyllode - Acacia
B. Leaf spine - Pea
C. Storage leaf - Onion
D. Leaf pitcher - Nepenthes

Answer

To solve the question of selecting the incorrect match from the given options, we will analyze each option one by one.

### Step-by-Step Solution:

1. **Option (a): Phyllode - Acacia**
- A phyllode is a flattened leaf or a leaf-like structure that performs photosynthesis. In Acacia, the leaflets are often reduced, and the petiole becomes flattened and green, functioning like a leaf.
- **Conclusion:** This is a correct match.

2. **Option (b): Leaf spine - Pea**
- Leaf spines are modified leaves that are typically found in xerophytic plants to reduce water loss. Pea plants (Pisum sativum) do not have leaf spines; instead, they have compound leaves with leaflets.
- **Conclusion:** This is an incorrect match.

3. **Option (c): Storage leaf - Onion**
- In onions (Allium cepa), the leaves are modified to store food in the form of carbohydrates. The fleshy leaves of onions serve as storage organs.
- **Conclusion:** This is a correct match.

4. **Option (d): Leaf pitcher - Nepenthes**
- Nepenthes, commonly known as pitcher plants, have modified leaves that form a pitcher shape to trap insects for nutrition. This adaptation is well-known and characteristic of the plant.
- **Conclusion:** This is a correct match.

### Final Answer:
The incorrect match from the given options is **(b) Leaf spine - Pea**.
