  2. What are some plants that don’t have flowers? ferns pine trees mosses

  3. Spore-producing Plants • Mosses and Ferns use spores to reproduce instead of seeds. Spore cases on the back of a fern Spore cases growing up from a moss

  4. Gymnosperms • Pine trees, fir trees, redwoods, sequoias and gingkos are all gymnosperms. They form seeds... White fir Giant sequoia White pine

  5. Gymnosperms • Fertilization happens in cones, not flowers. • Gymnosperms have seeds and cones, but don’t have fruit. • Angiosperms have seeds, flowers, and fruit.

  6. Vegetative Reproduction • Sometimes plants simply grow from an already existing plant. English ivy Potato

  9. Evolutionary History • 300 million years ago – The first seed-bearing plants (gymnosperms) appear. Seeds are an adaptation that allow these plants to spread to to dryer areas.

  10. Evolutionary History • >135 million years ago – Angiosperms develop and are now the most diverse kind of plant found on Earth. There are more kinds of flowering plants than any other kind of plant. How did flowering plants become so successful?
