  1. How Plants Are Classified Part 2: Reproduction 6-2.3: Compare the characteristic structures of various groups of plants (including vascular or nonvascular, seed or spore-producing, flowering or cone-bearing, and monocot or dicot).

  2. Link • Five fast things you know about seeds

  3. Essential Question ? What are the main ways scientists classify plants? You already know they are classified as vascular and non-vascular. The following classification can also be used to group plants.

  4. Seed Producing Plants • Seed-producing plants are plants that reproduce through seeds.Seed plants make their own seeds. • Seeds contain the plant embryo (the beginnings of roots, stems, and leaves) andstored food (cotyledons) and are surrounded by a seed coat. From those seeds, new plants grow.

  5. Seed Producing Plants • There are two major groups of seed-producing plants: cone-bearing plants (gymnosperm) and flowering plants (angiosperm).

  6. Seed ProducersThe Cone-Bearing Plants • Most cone-bearing plants are evergreen with needle-like leaves. • Conifers never have flowers but produce seeds in cones. These seeds are said to be “naked”. • Examples include pine, spruce, juniper, redwood, and cedar trees.

  7. Seed Producers: The Flowering Plants • Flowering plants differ from conifers because they grow their seeds inside an ovary, which is embedded in a flower. • The flower then becomes a fruit containing the seeds.

  8. Flowering Plants: Cont. • Examples include most trees, shrubs, vines, flowers, fruits, vegetables, and legumes (beans).

  9. The Non-Seed Producers: Spore Producing Plants • Spore-producing plants are plants that produce spores for reproduction instead of seeds.  • Spores are much smaller than seeds.  • Almost all flowerless plants produce spores. • Examples include mosses and ferns.

  10. Give 3 qualitative observations about fern spores? See Fern Spores Video

  11. Give 3 qualitative observations about moss spores? See Moss Spores Video

  12. Classify each picture as a seed producer or spore producer 1. 3. 2. 4. 5.

  13. SummarizeFollow the teacher to create a diagram comparing seed-producers to spore-producers. Seed Producers Spore Producers

  14. Answer EQ • Define key terms. • Seed • Spore • Conifer
