The correct Answer is:
To determine which properties are seen in Hibiscus rosa-sinensis, we will evaluate each of the given statements one by one. ### Step-by-Step Solution: 1. **Leaves with Alternate Phyllotaxy**: - Hibiscus rosa-sinensis exhibits leaves that are arranged alternately on the stem. This means that the leaves do not grow directly opposite each other but rather in a staggered pattern along the stem. - **Conclusion**: This statement is **true**. 2. **Polycarpellary Syncarpous Inferior Ovary**: - In Hibiscus rosa-sinensis, the ovary is actually **superior**, not inferior. The term "polycarpellary" refers to the presence of multiple carpels, which is correct, but since the ovary is not inferior, this statement is **false**. - **Conclusion**: This statement is **false**. 3. **Twisted Aestivation in Petals**: - The petals of Hibiscus rosa-sinensis exhibit twisted aestivation, which means that the petals overlap each other in a twisted manner when they are in bud form. - **Conclusion**: This statement is **true**. 4. **Basal Placentation of Ovules**: - Hibiscus rosa-sinensis does not have basal placentation; instead, it has axile placentation. This means that the ovules are attached to the central axis of the ovary. - **Conclusion**: This statement is **false**. ### Summary of the Findings: - (i) True: Leaves with alternate phyllotaxy - (ii) False: Polycarpellary syncarpous inferior ovary - (iii) True: Twisted aestivation in petals - (iv) False: Basal placentation of ovules ### Final Answer: The properties seen in Hibiscus rosa-sinensis are (i) and (iii). ---
