The correct Answer is:
To solve the question regarding the characters not applicable to the family Solanaceae, we will analyze each option based on the characteristics of the Solanaceae family. ### Step-by-Step Solution: 1. **Understanding the Family Solanaceae**: - The Solanaceae family, also known as the nightshade family, includes plants like potatoes, tomatoes, and eggplants. - They typically have actinomorphic (radially symmetrical) flowers, are bisexual, and have specific floral structures. 2. **Analyzing Each Option**: - **(i) Epipetalous and syngenesious anthers**: - Epipetalous means the stamens are attached to the petals, which is true for Solanaceae. - Syngenesious refers to anthers that are fused together, which is **not true** for Solanaceae, as the anthers are free. - **Conclusion**: This option is partially correct but includes an incorrect characteristic (syngenesious). - **(ii) Bicarpellary and syncarpous ovary**: - This is true for Solanaceae. They have two carpels (bicarpellary) that are fused (syncarpous). - **Conclusion**: This option is applicable to Solanaceae. - **(iii) Oblique ovary with axile placentation**: - Solanaceae flowers typically have an oblique ovary, and they exhibit axile placentation. - **Conclusion**: This option is applicable to Solanaceae. - **(iv) Stamens six, arranged in two whorls**: - Solanaceae generally have five stamens, not six. - **Conclusion**: This option is incorrect for Solanaceae. - **(v) Bicarpellary, syncarpous and inferior ovary**: - While bicarpellary and syncarpous are correct, the ovary in Solanaceae is superior, not inferior. - **Conclusion**: This option is incorrect for Solanaceae. 3. **Final Assessment**: - The characters that are **not applicable** to the family Solanaceae are: - (i) Epipetalous and syngenesious anthers (due to syngenesious) - (iv) Stamens six, arranged in two whorls (due to the number of stamens) - (v) Bicarpellary, syncarpous and inferior ovary (due to inferior ovary) ### Answer: The characters not applicable to the family Solanaceae are (i), (iv), and (v).
