  1. Kingdom Plantae

  2. How Plants came to be

  3. Overview of the Plant Kingdom • Botanists divide the plant kingdom into four groups based on three important features: • Water conducting tissues • Seeds • Flowers

  4. Mosses

  5. Ferns

  6. Cone Bearing Plant

  7. Flowering plant

  8. The Plant Life Cycle • Plants have life cycles that are characterized by alternation of generations • The two generations are the haploid (N) gametophyte, or gamete-producing plant, and the diploid (2N) sporophyte, or spore-producing plant.

  9. Bryophytes • Type of early plant with no vascular tissue that draw water in their cells by osmosis.

  10. Moss

  11. Liverwort

  12. Hornwort

  13. In just a few million years, plants grew to a whole new scale on the landscape. Q: What caused this increase in size? A: Vascular Tissue

  14. Vascular tissue • A type of tissue that is specialized to conduct water and nutrients through the body of the plant

  15. Evolution of Vascular Tissue • Both forms of vascular tissue—xylem and phloem—can move fluids throughout the plant body, even against the force of gravity.

  16. Xylem • Carry water upwards from the roots to every part of the plant

  17. Phloem • Transports nutrients and carbohydrates produced by photosynthesis from the leaves down to the roots

  18. 22–3 Seedless Vascular Plants

  19. Club Mosses 

  20. Horsetails

  21. Ferns Underground Stem

  22. Over millions of years, plants with a single trait—the ability to form seeds—became the most dominant group of photosynthetic organisms on land. • Seed plants are divided into two groups:

  23. Gymnosperms • Cone plants • Bear their seeds directly on the surfaces of cones Ex.) conifers, pines, spruces, cycads, ancient ginkgoes and gnetophytes

  24. Angiosperms • Flowering plants • Bear their seeds within a layer of tissue that protects the seed Ex.) grasses, flowering trees shrubs, wild flowers

  25. Monocots and Dicots • Monocots and dicots are named for the number of seed leaves, or cotyledons, in the plant embryo. Monocots have one seed leaf, and dicots have two seed leafs

  26. Flowers • Seed bearing structures of angiosperms

  27. Pollen Entire Male Gamtophyte

  28. Pollen grain • Contains the male gamete

  29. Pollination • The transfer of pollen from the male gametophyte to the female gametophyte
