Make a sketch of the specimen and label the following structures: sporophyte, frond, pinna, rhizome, root (Alternatively, you can find a live fern with all these structures and take a picture, label it and upload here.)Draw the life cycle of a typica bryophyte such as moss. Your drawing should contain the following terms: 2N and N, Sporophyte and Gametophyte, Sporangium, Meiosis, Spores, Protonema, Antheridium, Sperm, Archegonium, Egg and FertilizationArchaeopteryx is an extinct tree fern. Select the correct response: True False
- Moss gametophyte and sporophyte Describe the colors of the structure and their textures. Indicate which structures are haploid and diploid. Compare the morphology of the moss with the brown algae, polysiphonia, and spirogyra. What's the ecology of mosses and why are they sometimes called natures compass?Gametophytes develop into gametes and sporophytes develop into spores. True False In mosses and ferns, fertilization, and zygote and embryo formation occur in antheridia. True False Which of the following structures are in an archegonium of a moss? sterile jacket venter neck spermatogenous cells Ferns have roots and vascular tissues but mosses don't. True FalseByrophytes are usually found in areas that are very wet or damp at least part of the year. Which of the following statements describes characteristics of byrophytes that make them dependent on water? State all that numbers that apply. 1. They have a dominant gametophyte phase. 2. They have swimming sperm that need water so they can swim to fertilize the eggs of other nearby plants. 3. They do not have lignin-stiffened vascular tissue or roots to effectively distribute water throughout the plant.
- The alteration of generations comes from the fact that the sporophyte generation and gametophyte generation occur alternately. True False The gametophytes of mosses are much smaller than their sporophytes. True False Gametophytes develop into gametes and sporophytes develop into spores.
