Presentation Transcript

  1. Kingdom Plantae…aka Plants!

  2. Plants: • many shapes, sizes, & internal structures • 2 phyla for plants: • tracheophytes = vascular tissue ( true roots, leaves and stems) • Seedless • Seeded • bryophytes = nonvascular plants ( no true roots, stems, leaves) • Provide most living things with food & O2 • Are Autotrophs • Are Eukaryotes

  3. Non Vascular Plants • A.k.a- Bryophytes • Low growing plants • Lack vacular tissue • Xylem- tubes transport water • Phloem – tubes transport food…GLUCOSE!

  4. Characteristics: • Autotrophs • Multi-cellular • Asexual reproduction • spores • Sexual reproduction • Sperm and egg cells • Require water to reproduce • Eukaryotic

  5. Examples Include: • Mosses Liverworts Hornworts

  6. Vascular Plants • A.k.a…Tracheopytes • Contain true roots, leaves and stems • Have vascular bundles • Can be seedless • Can be seeded

  7. Non seeded vascular plants • Have vascular tissue • Do not use seeds to reproduce • Ex. Horsetails, & Ferns

  8. Seeded Plants: • Have vascular tissue • Produce seeds (to reproduce) 1. Gymnosperms: • Cone bearing plants 2. Angiosperms: • Flower bearing plants

  9. Characteristics of Seeded Plants: • Seeds made up of: • Embryo – fertilized seed: develop into the young plants • Stored food • Seed coat

  10. Gymnosperms: • Produce “naked seeds” • No fruit covering • Needlelike/scale-like leaves • Cones are reproductive structures • Male and female cones • Include cycads, ginkos, gnetophytes and conifers

  11. Cycad

  12. Ginko biloba

  13. Angiosperms • Flowering plants • Plants which produced seeds which are protected by fruit • 2 categories: • Monocots • Dicots

  14. Monocots: • Having only one seed leaf or cotyledon • Leaves have parallel veination • Flower petals in 3’s or multiple of 3’s • Scattered Vascular bundles within the stem ( cross section)

  15. Dicot: • Having 2 seed leaves or cotlyledons • Netted veinetion • Flowers in 4/5’s or multiples of 4/5’s • Vascular bundles are arranged wihtin the stem (cross section)

  16. Monocot vs. DicotVenation: Parallel venation Net venation

  17. Monocot vs DicotFlowers 3’s or multiple of 3’s 4/5’s or multiple of 4/5’s

  18. Monocot vs. Dicot 1 cotyledon 2 cotyledon

  19. REMEMBER!!! • Cells are different from animal cells: • plants have cell wall and animal cells do not b. vacuole large in plants, small in animal cells c. plants have chloroplasts, animal cells do not
