    1. PolysiphoniaPolysiphonia

    2. Lecture 5 Bryophytes

    3. Transitions - Life On Land Obstacles Desiccation Dispersal - moving around gametes and spores Moving water and nutrients into and around the plant body Structural Support plant body outside of water Some key innovations are observed in the Bryophytes

    4. Bryophytes General to Bryophytes Multicellular sporophyte but, gametophyte is the predominant phase and in many the sporophyte is quite dependent on the gametophyte for water, nutrients, etc. Swimming sperm water is required for reproduction

    5. Filaments of algae-like strands that suggest a green algal ancestor Found in some liverworts and mossesFilaments of algae-like strands that suggest a green algal ancestor Found in some liverworts and mosses

    27. Bryophyta (Mosses) 9500 species with more than 400 in Sphagnum. Sporophyte can be fairly large, but still generally dependent on the gametophyte. Sphagnum important globally holds tremendous amounts of C02.

    39. Economic importance of Sphagnum Peatlands store C (400 million metric tons) C storage removes CO2 from the atmosphere Dried peat is used as industrial and residential fuel Used to absorb water

    40. Couple at the right are from the Netherlands preserved since the iron age Over the years, peat cutters working the bogs of northwest Europe have uncovered hundreds of mummies. The spongy top layer of a peat bog tends to seal off oxygen from the layers below. A bog's naturally acidic environment also helps to create mummies, giving them a distinctively brown, leathery and lifelike appearance. The oldest "bog mummies" are from the Iron Age (between 400 BC and 400 AD) and are thought to have been the Celtic or Germanic contemporaries of the Romans. Strangely, many of the mummies found in the European bogs show evidence of violent deaths. With slit throats and broken skulls, these individuals may have been victims of ritual sacrifice, just like the mummies of China's Takla Makan Desert.

    46. Conclusions The transition to land has started, we have seen terrestrial plants with Cuticle Multicellular sporophyte retained on gametophyte Spore dispersal through the air Rhizoids Stomata Archegonia (special structure holding a single egg) Thursday we will start looking at the development of Vascular tissue Support for upward growth
