Phyllode (Phythode) is leaf like and derived from

Options

A. stem
B. root
C. petiole and rachis
D. bud

Answer

### Step-by-Step Solution:

1. **Definition of Phyllode**:
- A phyllode is a modified structure that resembles a leaf. It is typically a flattened, leaf-like stem or petiole that performs the functions of a leaf.

2. **Origin of Phyllode**:
- Phyllodes are derived from the petiole (the stalk that attaches the leaf blade to the stem). In some plants, the actual leaves may be reduced or absent, and the phyllode takes over the role of photosynthesis.

3. **Function of Phyllode**:
- The primary function of a phyllode is to carry out photosynthesis, similar to a regular leaf. It allows the plant to survive in environments where leaves may not be as effective.

4. **Examples of Phyllode**:
- A common example of a plant with phyllodes is the Acacia. In these plants, the phyllodes are often flattened and green, serving the purpose of leaves.

5. **Conclusion**:
- In the context of the question, the phyllode is derived from the petiole and is a modification of the stem. Therefore, the correct answer is that phyllodes are derived from the petiole.

### Final Answer:
Phyllode is leaf-like and derived from the petiole.
