The correct Answer is:
To answer the question "Placenta of a flower is a tissue that," we need to analyze the options provided and understand the role of the placenta in a flower. ### Step-by-Step Solution: 1. **Understanding Placenta in Flowers**: - The placenta in a flower is a specialized tissue that connects the ovules (future seeds) to the ovary wall. It plays a crucial role in the development of seeds. 2. **Analyzing the Options**: - **Option 1: Pollen grains**: This is incorrect. Pollen grains are produced in the anthers and are not related to the placenta. - **Option 2: Attaches stem cells with corolla or sepals**: This is also incorrect. The corolla (petals) and sepals are parts of the flower structure but do not relate to the function of the placenta. - **Option 3: Ovules**: This option is correct. The placenta is indeed the tissue that bears the ovules, which develop into seeds after fertilization. - **Option 4: Corolla**: This is incorrect. The corolla refers to the petals of the flower and is not connected to the function of the placenta. 3. **Conclusion**: - Based on the analysis of the options, the correct answer is that the placenta of a flower is a tissue that bears the ovules. ### Final Answer: The placenta of a flower is a tissue that bears the ovules. ---
