The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Chasmogamy**: Chasmogamy is a type of pollination mechanism in flowering plants where the flowers are open and expose their reproductive organs to facilitate pollination. 2. **Contact of Sex Organs**: In chasmogamy, the sex organs (stamens and pistils) come into contact with each other through processes such as growth, bending, or folding. This allows for the transfer of pollen from the male parts to the female parts. 3. **Position of Flowers**: The question specifically asks about the position of the flowers during chasmogamy. It is important to note that in chasmogamous flowers, the petals are open, allowing for easy access to the reproductive organs. 4. **Evaluating Options**: The options given are: - Open position - Closed position - Fragrant - Bright colored Since chasmogamy involves flowers that are open to facilitate pollination, the correct answer is "open position". 5. **Conclusion**: Therefore, in chasmogamy, the flowers are always in an open position. **Final Answer**: The flowers are always in the open position during chasmogamy. ---
