Placentation of Pea flower is

Options

A. Parietal
B. Marginal
C. Axile
D. Superficial

Answer

To determine the type of placentation in a pea flower, we can follow these steps:

1. **Understand the Concept of Placentation**: Placentation refers to the arrangement of ovules within the ovary of a flower. Different types of placentation include parietal, marginal, axile, and superficial.

2. **Identify the Structure of the Pea Flower**: The pea flower (Pisum sativum) has a single-chambered ovary. This is an important characteristic that helps in identifying the type of placentation.

3. **Analyze the Arrangement of Ovules**: In the pea flower, the ovules are arranged along the suture of the ovary wall. This specific arrangement indicates a particular type of placentation.

4. **Determine the Type of Placentation**: Since the ovules are arranged in a row along the suture of the ovary wall, this is classified as marginal placentation.

5. **Review Other Types of Placentation**: To reinforce the understanding, it is helpful to compare with other types of placentation:
- **Parietal Placentation**: Found in cucurbits (like cucumber).
- **Axile Placentation**: Seen in plants of the Solanaceae family (like tomatoes).
- **Superficial Placentation**: Observed in water lilies.

6. **Conclude the Answer**: Based on the analysis, the correct answer for the type of placentation in a pea flower is marginal placentation.
