The correct Answer is:
To answer the question about the shape of the thalamus of a hypogynous ovary, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Thalamus**: The thalamus, also known as the receptacle, is the thickened part of the stem (pedicel) where the floral organs (petals, sepals, stamens, and carpels) are attached. 2. **Identify the Type of Ovary**: The question specifies a hypogynous ovary. In a hypogynous flower, the ovary is positioned above the other floral parts (such as petals and sepals). 3. **Determine the Shape Based on Ovary Position**: The shape of the thalamus is influenced by the position of the ovary: - In hypogynous flowers (superior ovary), the thalamus is typically **convex**. - In epigynous flowers (inferior ovary), the thalamus can be flat or cup-shaped. - In perigynous flowers, the thalamus may also have a different shape but is not relevant for this question. 4. **Conclude the Correct Option**: Since the question asks for the shape of the thalamus in a hypogynous ovary, and we established that it is convex, the correct answer is **convex**. ### Final Answer: The thalamus of a hypogynous ovary is **convex**. ---
