  1. Evolution of Plant Kingdom

  2. Bryophytes

  3. Nonvascular plants - lack vascular tissue Rely on osmosis to draw in water, which keeps these mosses relatively small. Lack true roots, have rhizoids to anchor to the ground. Rely on water for reproduction Mosses

  4. Ferns

  5. Seedless vascular plants -have vascular tissue including true roots, stems, and leaves Vascular tissue allows ferns to transport nutrients against gravity, more efficient than diffusion Require water for reproduction Ferns

  6. Gymnosperms

  7. Vascular plants that bear seeds directly on the surface of cones No longer dependent on water for reproduction, embryos are also protected by the seed Include Gnetophytes, Cycads, Ginkgoes, and Conifers Gymnosperms

  8. Reproductive organs known as flowers to protect the seed Fruit is a thick wall of tissue surrounding the seed Flowers and Fruits have lead to the great success of the Angiosperms Angiosperms
