The correct Answer is:
To answer the question about the spermatozoid of Cycas, we will analyze the characteristics of the spermatozoids in this plant. ### Step-by-Step Solution: 1. **Understanding Spermatozoids**: Spermatozoids are the male gametes in plants. In the case of Cycas, which is a genus of cycads, the structure and characteristics of these gametes are important. 2. **Identifying the Type of Spermatozoid**: The options provided are biflagellate, non-flagellate, uniflagellate, and multiflagellate. We need to determine which of these accurately describes the spermatozoids of Cycas. 3. **Characteristics of Cycas Spermatozoids**: - Cycas spermatozoids are known to be motile. - They are described as being top-shaped and naked (without any covering). - Importantly, they possess multiple flagella. 4. **Flagella Arrangement**: The flagella of Cycas spermatozoids are arranged in spirals, typically in groups of 4 to 5. This indicates that they are not just biflagellate (two flagella) or uniflagellate (one flagellum), but rather multiflagellate. 5. **Conclusion**: Based on the characteristics outlined, the correct answer to the question is that the spermatozoid of Cycas is **multiflagellate**. ### Final Answer: The spermatozoid of Cycas is multiflagellate. ---
