Which of the following is not a character of phyllode?

Options

A. Leaf like structure formed by petiole
B. Axillary bud present in axil
C. Do not possess nodes and internodes
D. Mostly succulent and present in Opuntia

Answer

To determine which of the following is not a character of phyllode, we need to analyze each option provided in the question. Here’s a step-by-step solution:

### Step 1: Understand what a phyllode is
A phyllode is a modified petiole (the stalk that attaches the leaf blade to the stem) that takes on a leaf-like appearance and function. It is typically found in xerophytic plants, which are adapted to dry environments.

### Step 2: Analyze the options
1. **Leaf-like structure formed by petiole**: This statement is true. Phyllodes are indeed leaf-like structures that originate from the petiole.

2. **Axillary bud present in axil**: This statement is also true. Since phyllodes are modified petioles, they will have axillary buds in their axils.

3. **Do not possess nodes and internodes**: This statement is true as well. Phyllodes, being modified petioles, do not have nodes and internodes like typical leaves do.

4. **Most succulent and present in Opuntia**: This statement is false. The succulent structures in Opuntia (a genus of cacti) are known as phylloclades, which are modified stems, not phyllodes.

### Step 3: Conclusion
The option that is not a character of phyllode is the fourth statement: "most succulent and present in Opuntia." This is because Opuntia has phylloclades, which are different from phyllodes.

### Final Answer
The correct answer is: **Most succulent and present in Opuntia**.
