Phyllode is present in :

Options

A. Asparagus
B. Euphorbia
C. Australian Acacia
D. Opuntia

Answer

To solve the question "Phyllode is present in:", we will follow these steps:

### Step 1: Understand what a phyllode is
A phyllode is a modification of the petiole (the stalk that attaches the leaf blade to the stem) into a flattened and wide structure. This adaptation allows the petiole to perform photosynthesis, similar to the leaf lamina.

**Hint**: Remember that a phyllode is not a leaf but a modified petiole.

### Step 2: Identify the function of a phyllode
The primary function of a phyllode is to carry out photosynthesis. In plants where phyllodes are present, the flattened structure takes over the role of the leaf.

**Hint**: Consider the role of photosynthesis in plants and how modifications can help in this process.

### Step 3: Look at the parts of a leaf
A typical leaf consists of three main parts: the leaf base, the petiole, and the lamina. In the case of phyllodes, the petiole is modified.

**Hint**: Recall the structure of a leaf and where the petiole fits into that structure.

### Step 4: Examine examples of plants with phyllodes
One of the well-known plants that exhibit phyllodes is the Australian Acacia. In this plant, the petiole is modified into a flattened structure that performs the function of a leaf.

**Hint**: Think about specific examples of plants that have unique adaptations.

### Step 5: Evaluate the options provided
The question provides multiple options. We need to identify which one corresponds to the presence of phyllodes. Based on our understanding, we can eliminate options that are known for other modifications, such as cladodes in Asparagus and Euphorbia.

**Hint**: Focus on the characteristics of each option and match them with what you know about phyllodes.

### Conclusion
After evaluating the options, the correct answer is **Australian Acacia**, as it is known for having phyllodes.

**Final Answer**: Australian Acacia
