Please also find an accompanying Biocam Poster for both the moss and the fern at each station to supplement the respective powerpoints. Complete the questions on the other side of this page when you are finished filling in the chart. Moss & Fern Mosses Ferns Comparisons 1. Produces eggs 2. Produces sperm 3. Sporophyte independent (Yes or No?) 4. Structure producing spores 5. Spores germinate into: 6. Inconspicuous (hardly noticeable) Generation 7. Conspicuous Generation 8. Medium for fertilization 9. Agent for spore dispersal 10. First cell of sporophyte 11. First cell of gametophyte 12. General habitat Questions for further study: FERNS 1. Are spores haploid or diploid? 2. Spores are produced by what process? How are they spread? 3. What visible part of the fern grows from the rhizome? 4. What are fiddleheads? 5. Using your textbook (pg. 393), label the stages and structures of the fern life cycle identified on the diagram below. MOSSES 1. Why is the antheridial head shaped like a cup? 2. Why must moss sperm have flagella? 3. Why is the sporophyte generation elevated above the gametophyte generation? 4. Why don’t mosses grow taller? 5. What process ends the gametophyte generation? The sporophyte generation? 6. Is the mature moss plant haploid or diploid? 7. Using your textbook (pg. 392), label the stages & structures of the fern life cycle identified on the diagram below.
