Ferns - HW 2 Answer the following questions relating to Ferns. 1. Are the spores produced by the fern sporophyte formed by meiosis or mitosis? 2. Do the spores belong to the gametophyte or sporophyte generation? 3. Are the gametes produced by mitosis or meiosis? 4. Are the archegonia and antheridia haploid or diploid? Think about which generation produces them. 5. Is the dominant generation for the fern the gametophyte or sporophyte? 6. Can you suggest any ecological role for ferns? Find the answer on the internet. 7. Which parts of the fern life cycle are haploid? 8. Which parts of the fern life cycle are diploid? 9. How could you determine that rhizomes are stems and not roots? 10. Where are the male and female structures located on the heart shaped prothallus? Attached find a Dichotomus Key to the different Genera of Common Ferns. What is a Dichotomus Key? What is the purpose of a Dichotomus Key?
