The correct Answer is:
To determine the type of embryo sac in Polygonum, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Question**: The question asks about the type of embryo sac found in Polygonum, specifically how many cells it contains. 2. **Review Embryo Sac Structure**: In flowering plants (angiosperms), the embryo sac is typically formed from the megaspore and undergoes mitotic divisions to develop into a mature structure. 3. **Identify the Polygonum Type**: The Polygonum type of embryo sac is characterized by specific cellular arrangements and is known to be a common type among angiosperms. 4. **Count the Cells**: The mature Polygonum embryo sac is 8-nucleate but is organized into 7 cells. This includes: - 1 egg cell - 2 synergids - 3 antipodal cells - 1 central cell (which contains 2 polar nuclei) 5. **Conclusion**: Therefore, the correct answer to the question is that the Polygonum type of embryo sac is 7 cells. ### Final Answer: The Polygonum type of embryo sac is **7 cells** (Option D). ---
