  1. Domain Bacteria Domain Archaea Domain Eukarya Common ancestor Kingdom: Plants Photosynthetic Eukaryotes

  2. Plant Diversity Mossesno watertransportsystem(pipes) Fernswater transport, no seeds Coniferspollen & seeds Flowering plantsflowers & fruit seed plants water transport system colonization of land

  3. Mosses • Characteristics • no water transport system • no true roots • swimming sperm • need water to reproduce • spores for reproduction • no seeds Where mustmosses live?

  4. Cones & “naked” seeds

  5. Flowering plants • Characteristics • water transport system • xylem, roots • flower • specialized structure for sexual reproduction • pollen • sperm that doesn’t have to swim • seeds within fruit

  6. Angiosperm: flowering plants

  7. Stigma Carpel Style Anther Ovary Stamen Filament Petal Ovule Sepal Flower • 4 rings of flower parts • sepals • petals • stamens • male • carpel or pistil • female

  8. Identify the flower structures…

  9. Flower variations

  10. Co-evolution: flowers & pollinators How a bee sees a flower…insects see UV light = a bulls-eye to the nectar

  11. Angiosperm: fruiting plants

  12. Other fruits…

  13. Seed & Plant embryo seed coat • Seed offers… • protection for embryo (new plant) • stored nutrients for growth of new plant food for new plant seed leaves embryo(new plant) “seed” leaves = first leaves of new plant

  14. Any Questions??
