  1. Nonvascular Plants and Seedless Vascular Plants BSC 2011L

  2. Plants • Domain Eukarya • Kingdom Plantae • “Bryophytes” - nonvascular seedless plants • Phylum Hepatophyta Liverworts • Phylum Anthocerotophyta Hornworts • Phylum Bryophyta Moss • “Vascular Seedless Plants” • Phylum Lycopodophyta Club Moss • Phylum Monilophyta Wisk fern • Phylum Monilophyta Horsetails • Phylum Monilophyta Ferns

  3. Alternation of Generations • Sporophyte Generation • Produces haploid spores by meiosis • Gametophyte Generation • Produces gametes by mitosis

  4. Nonvascular Seedless Plants • No vascular tissue • Must remain small • Mosses, liverworts, and hornworts • Gametophyte generation is dominant • Produces eggs in archegonia • Produces flagellated sperm in antheridia • Rely on water source for reproduction Notice the gemmae cups In this liverwort

  5. Vascular Seedless Plants • Whisk ferns, club mosses, horsetails, and ferns • Sporophyte generation is dominant • Adaptations for living on land • Vascular tissue • Windblown spores

  6. What is a Thallus? • Body of a lower plant that has no recognizable shoot, root, or leaf regions • Fern prothallus - gametophyte Young sporophyte emerging from prothallus

  7. Vascular Seedless PlantsCross Section of Frond Leaflet • Sporophyte Generation • Look at Figure 16.15 • The sorus contains the sporangium where the spores are produced
