  1. Chapters 22-24 Kingdom Plantae

  2. Cell type • Cell organization • MoN • Mostly terrestrial, some aquatic • Cell walls made of General Characteristics

  3. What Plants Need to survive • gas exchange, and movement of water

  4. Fungi Protozoans Algae Bacteria Which group do scientists believe plants evolved from?

  5. Floweringplants Cone-bearingplants Ferns andtheir relatives Flowers; SeedsEnclosed in Fruit Mosses andtheir relatives Seeds Water-Conducting(Vascular) Tissue Green algaeancestor Evolution of Plants

  6. low-growing (“carpet-like”), found in moist areas • No seeds • No vascular tissue Mosses

  7. No seeds • Have vascular tissue – specialized tissues to transport water, minerals, and nutrients • Xylem – transports water from roots to leaves • Phloem – transports nutrients from leaves to roots • Allowed the formation of ROOT, STEMS, and LEAVES • Allows plants to grow TALLER! Ferns

  8. absorbs water and minerals from soil anchors plant into ground. Roots

  9. structural support for upright growth Stems

  10. carries out most photosynthesis Leaf

  11. reproduce by forming spores on underside of leaves Reproduction is dependent on water – sperm must swim to the egg Ferns

  12. Contain adaptations that allow plants to reproduce without water: Flowers or cones (gametes grow within these), transfer of sperm by pollen, seeds that house embryo Gymnosperms & Angiosperms

  13. produce pollen - contains the male gamete (sperm) • Pollination – pollen grain is carried to egg Pollen

  14. Contains zygote or embryo, food supply and protective coat (seed coat) to prevent drying out seeds Seed coat embryo Food supply

  15. Seeds allow offspring of plants to be dispersed to new locations by wind, water, and animals  increases BIODIVERSITY! Seeds (cont)

  16. Gymnos = naked sperma = seed • ex-cedar, cypress, pine, & spruce Gymnosperms

  17. female & male cones— most are wind pollinated where pollen is carried by wind from male cone to female cone Pollination in Gymnosperms

  18. Have flowers – reproductive structure brightly colored or heavily scented to attract pollinators • Pollination occurs through animals Angiosperms (“Enclosed seeds”)

  19. Flower Parts male flower part - Stamen Carpel/pistil - female flower part stigma style Anther- produces pollen Filament Petal ovary Ovule (egg) Sepals-modified leaves Pg. 612

  20. Have fruit • After fertilization, the ovary of the flower develops into the fruit • Purpose is seed dispersal – when animals eat fruit and then defecate, seeds are passed. THIS IS THE REASON FRUITS EXIST! Angiosperms (cont.)

  21. kiwi lettuce tomato pumpkin strawberry 7. Which of the following is NOT a fruit?
