The correct Answer is:
To solve the question regarding the nature of antherozoids in ferns, we can break down the information step by step. ### Step-by-Step Solution: 1. **Understand the Context of Ferns**: - Ferns are vascular plants that reproduce through spores and do not produce seeds or flowers. - They have a dominant sporophyte phase in their life cycle, which is crucial for understanding their reproductive structures. 2. **Identify the Structure of Antherozoids**: - Antherozoids are the male gametes produced in ferns. - They are formed in a structure called antheridium, which is haploid. 3. **Characteristics of Antherozoids**: - Antherozoids in ferns are described as spherical and coiled. - They are also noted to be multiflagellated, meaning they possess multiple flagella. 4. **Evaluate the Options**: - The options provided are: - Non-motile - Uniflagellate - Biflagellate - Multiflagellate - Based on the characteristics discussed, we can eliminate the first three options: - Non-motile: Antherozoids are motile due to their flagella. - Uniflagellate: This implies only one flagellum, which is incorrect. - Biflagellate: This implies two flagella, which is also incorrect. 5. **Conclusion**: - The correct answer is **multiflagellate**, as antherozoids in ferns have multiple flagella, allowing them to be motile. ### Final Answer: The antherozoids of fern are **multiflagellate**. ---
