Axile placentation is present in

Options

A. Argemone
B. Dianthus
C. Lemon
D. Pea

Answer

**Step-by-Step Text Solution:**

1. **Understanding Placentation:**
- Placentation refers to the arrangement of ovules within the ovary of a flower. It is important to identify the type of placentation to answer the question correctly.

2. **Analyzing the Options:**
- The options provided are Argemone, Dianthus, Lemon, and Bean. We need to evaluate each option to determine which one exhibits axile placentation.

3. **Evaluating Argemone:**
- Argemone has parietal placentation. In this type, the ovules develop on the inner wall of the ovary. Therefore, Argemone does not have axile placentation.

4. **Evaluating Dianthus:**
- Dianthus exhibits free central placentation. This means that the ovules are located on a central axis within the ovary. Thus, Dianthus does not have axile placentation.

5. **Evaluating Pea (Pisum):**
- Pea plants have marginal placentation, where the ovules are arranged along the ridge of the ovary. Therefore, pea does not have axile placentation.

6. **Evaluating Lemon:**
- Lemon has axile placentation. In axile placentation, the ovules are arranged around a central axis formed by the fusion of the septa in a compound ovary. This is the defining characteristic of axile placentation.

7. **Conclusion:**
- Based on the evaluations, the correct answer is Lemon, as it is the only option that exhibits axile placentation.

**Final Answer: Lemon has axile placentation.**
