The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Gymnosperms**: Gymnosperms are a group of seed-producing plants that include conifers, cycads, Ginkgo, and gnetophytes. They are characterized by having seeds that are not enclosed in an ovary (unlike angiosperms). 2. **Pollination Mechanism**: In gymnosperms, the process of pollination involves the transfer of pollen grains from the male reproductive structure (microsporangium) to the female reproductive structure (megasporangium). 3. **Pollen Grain Formation**: The microspore develops into a male gametophyte, which is highly reduced and forms the pollen grain. This pollen grain must reach the megasporangium for fertilization to occur. 4. **Role of Wind in Pollination**: The transfer of pollen grains to the megasporangium is primarily facilitated by wind. This method of pollination is known as anemophily. 5. **Evaluating the Options**: - **Option 1: Anemophily** - Correct. This is the process of pollination by wind, which is the exclusive method in gymnosperms. - **Option 2: Hydrophily** - Incorrect. This refers to pollination by water, which is not applicable to gymnosperms. - **Option 3: Zoophily** - Incorrect. This refers to pollination by animals, which is not a method used by gymnosperms. - **Option 4: Malacophily** - Incorrect. This refers to pollination by snails, which is also not relevant to gymnosperms. 6. **Conclusion**: The only correct answer is Option 1: Anemophily, as gymnosperms exclusively rely on wind for pollination. **Final Answer**: 1. Anemophily ---
