Two types of flowers are produced by

Options

A. Viola
B. Oxalis
C. Commelina
D. All of these

Answer

**Step-by-Step Solution:**

1. **Identify the Types of Flowers**: Understand that the question refers to two types of flowers produced by certain plants. The two types are Chasmogamous flowers and Clostrogamous flowers.

2. **Define Chasmogamous Flowers**: Chasmogamous flowers are those that have exposed anthers and stigmas, allowing for cross-pollination with other flowers. These flowers are open and can interact with pollinators.

3. **Define Clostrogamous Flowers**: Clostrogamous flowers, on the other hand, remain closed and do not open. They typically self-pollinate since there is no exposure to external pollinators.

4. **Identify the Plants**: The question lists three plants: Viola, Oxalis, and Comelina. Research or recall that all three of these plants can produce both types of flowers.

5. **Conclusion**: Since all three plants (Viola, Oxalis, and Comelina) produce both Chasmogamous and Clostrogamous flowers, the correct answer to the question is "all of the above."

**Final Answer**: All of these (Viola, Oxalis, and Comelina) produce two types of flowers.
