Common pansy has :

Options

A. Cleisotgamous flowers
B. Chasmogamous flowers
C. Unisexual flowers
D. Both (A) and (B)

Answer

**Step-by-Step Solution:**

1. **Identify the Plant**: The question refers to the Common Pansy, which is a flowering plant belonging to the family Violeteae.

2. **Types of Flowers**: Common Pansy produces two types of flowers:
- **Clistogamous Flowers**: These flowers do not open at maturity. They undergo self-pollination since fertilization occurs within the closed flower.
- **Clasmogamous Flowers**: These flowers open at maturity, allowing for cross-pollination between different plants.

3. **Pollination Mechanisms**:
- In Clistogamous flowers, since they remain closed, cross-pollination is not possible, and fertilization occurs within the same flower (self-pollination).
- In Clasmogamous flowers, the opening allows for pollen from one flower to fertilize another flower, promoting genetic diversity through cross-pollination.

4. **Conclusion**: Both types of flowers are present in the Common Pansy, allowing for both self-pollination and cross-pollination. This dual mechanism helps the plant adapt to various conditions, including disease resistance and genetic variation.

5. **Correct Answer**: Therefore, the correct option is "Both A and B," indicating that Common Pansy has both Clistogamous and Clasmogamous flowers.
